Subject: [PATCH] nvmem: layouts: store owner from modules with
|
||||
nvmem_layout_driver_register()
|
||||
|
||||
Modules registering driver with nvmem_layout_driver_register() might
|
||||
forget to set .owner field. The field is used by some of other kernel
|
||||
parts for reference counting (try_module_get()), so it is expected that
|
||||
drivers will set it.
|
||||
|
||||
Solve the problem by moving this task away from the drivers to the core
|
||||
code, just like we did for platform_driver in
|
||||
commit 9447057eaff8 ("platform_device: use a macro instead of
|
||||
platform_driver_register").

|
||||
|
||||
devm_device_add_groups() is being removed from the kernel, so move the
|
||||
nvmem driver to use device_add_groups() instead. The logic is
|
||||
identical, when the device is removed the driver core will properly
|
||||
clean up and remove the groups, and the memory used by the attribute
|
||||
groups will be freed because it was created with dev_* calls, so this is
|
||||
functionally identical overall.

Subject: [PATCH] nvmem: lpc18xx_eeprom: Convert to platform remove callback
|
||||
returning void
|
||||
MIME-Version: 1.0
|
||||
Content-Type: text/plain; charset=UTF-8
|
||||
Content-Transfer-Encoding: 8bit
|
||||
|
||||
The .remove() callback for a platform driver returns an int which makes
|
||||
many driver authors wrongly assume it's possible to do error handling by
|
||||
returning an error code. However the value returned is ignored (apart
|
||||
from emitting a warning) and this typically results in resource leaks.
|
||||
|
||||
To improve here there is a quest to make the remove callback return
|
||||
void. In the first step of this quest all drivers are converted to
|
||||
.remove_new(), which already returns void. Eventually after all drivers
|
||||
are converted, .remove_new() will be renamed to .remove().
|
||||
|
||||
Trivially convert this driver from always returning zero in the remove
|
||||
callback to the void returning variant.

Subject: [PATCH] nvmem: rmem: Fix return value of rmem_read()
|
||||
|
||||
reg_read() callback registered with nvmem core expects 0 on success and
|
||||
a negative value on error but rmem_read() returns the number of bytes
|
||||
read which is treated as an error at the nvmem core.
|
||||
|
||||
This does not break when rmem is accessed using sysfs via
|
||||
bin_attr_nvmem_read()/write() but causes an error when accessed from
|
||||
places like nvmem_access_with_keepouts(), etc.
|
||||
|
||||
Change to return 0 on success and error in case
|
||||
memory_read_from_buffer() returns an error or -EIO if bytes read do not
|
||||
match what was requested.

Subject: [PATCH] nvmem: meson-efuse: Fix return value of nvmem callbacks
|
||||
|
||||
Read/write callbacks registered with nvmem core expect 0 to be returned
|
||||
on success and a negative value to be returned on failure.
|
||||
|
||||
meson_efuse_read() and meson_efuse_write() call into
|
||||
meson_sm_call_read() and meson_sm_call_write() respectively which return
|
||||
the number of bytes read or written on success as per their api
|
||||
description.
|
||||
|
||||
Fix to return error if meson_sm_call_read()/meson_sm_call_write()
|
||||
returns an error else return 0.

data than the main attribute itself.
|

For example if nvme_config::root_only was set, the cell attribute

would still provide read access to everybody.

Mask out permissions not available on the main attribute.

Subject: [PATCH] nvmem: layouts: store owner from modules with
|
||||
nvmem_layout_driver_register()
|
||||
|
||||
Modules registering driver with nvmem_layout_driver_register() might
|
||||
forget to set .owner field. The field is used by some of other kernel
|
||||
parts for reference counting (try_module_get()), so it is expected that
|
||||
drivers will set it.
|
||||
|
||||
Solve the problem by moving this task away from the drivers to the core
|
||||
code, just like we did for platform_driver in
|
||||
commit 9447057eaff8 ("platform_device: use a macro instead of
|
||||
platform_driver_register").

devm_device_add_groups() is being removed from the kernel, so move the
|
||||
nvmem driver to use device_add_groups() instead. The logic is
|
||||
identical, when the device is removed the driver core will properly
|
||||
clean up and remove the groups, and the memory used by the attribute
|
||||
groups will be freed because it was created with dev_* calls, so this is

functionally identical overall.

Subject: [PATCH] nvmem: lpc18xx_eeprom: Convert to platform remove callback
|

returning void

Content-Type: text/plain; charset=UTF-8

|
||||
The .remove() callback for a platform driver returns an int which makes
|
||||
many driver authors wrongly assume it's possible to do error handling by
|
||||
returning an error code. However the value returned is ignored (apart
|
||||
from emitting a warning) and this typically results in resource leaks.
|
||||
|
||||
To improve here there is a quest to make the remove callback return
|
||||
void. In the first step of this quest all drivers are converted to
|
||||
.remove_new(), which already returns void. Eventually after all drivers
|
||||
are converted, .remove_new() will be renamed to .remove().
|
||||
|
||||
Trivially convert this driver from always returning zero in the remove
|
||||
callback to the void returning variant.

Subject: [PATCH] nvmem: layouts: store owner from modules with
|
||||
nvmem_layout_driver_register()
|
||||
|
||||
Modules registering driver with nvmem_layout_driver_register() might
|
||||
forget to set .owner field. The field is used by some of other kernel
|
||||
parts for reference counting (try_module_get()), so it is expected that
|
||||
drivers will set it.
|
||||
|
||||
Solve the problem by moving this task away from the drivers to the core
|
||||
code, just like we did for platform_driver in
|
||||
commit 9447057eaff8 ("platform_device: use a macro instead of
|
||||
platform_driver_register").

devm_device_add_groups() is being removed from the kernel, so move the

nvmem driver to use device_add_groups() instead. The logic is

identical, when the device is removed the driver core will properly

clean up and remove the groups, and the memory used by the attribute

groups will be freed because it was created with dev_* calls, so this is

functionally identical overall.

Subject: [PATCH] nvmem: meson-mx-efuse: Remove nvmem_device from efuse struct
|
||||
|
||||
nvmem_device is used at one place while registering nvmem
|
||||
device and it is not required to be present in efuse struct
|
||||
for just this purpose.
|
||||
|
||||
Drop nvmem_device and manage with nvmem device stack variable.
