Subject: [PATCH] drm/mipi-dbi: Add driver_private member to struct
|
||
|
|
mipi_dbi_dev

commit 1e7e8e1 upstream.
|
||
|
|
|
||
|
|
devm_drm_dev_alloc() can't allocate structures that embed a structure
|
||
|
|
which then again embeds drm_device. Workaround this by adding a
|
||
|
|
driver_private pointer to struct mipi_dbi_dev which the driver can use for
|
||
|
|
its additional state.

||
