Use device_set_node to make sure OF node gets assigned on block
devices to be used as NVMEM providers. While block partitions were
already working fine as NVMEM providers, bare block devices such as
mmcblk0boot1 will not work without this change.
Fixes: fc153aa8d9 ("kernel: import pending patches adding support for NVMEM on UBI and MMC")

Subject: [PATCH 14/15] mmc: block: set fwnode of disk devices
|
|
|
|
Set fwnode of disk devices to 'block', 'boot0' and 'boot1' subnodes of
|
|
the mmc-card. This is done in preparation for having the eMMC act as
|
|
NVMEM provider.
