Subject: add removed helper syscon_regmap_lookup_by_pdevname
|
|
|
|
The helper syscon_regmap_lookup_by_pdevname has been removed in 29d14b668d2f
|
|
("mfd: Remove unused helper syscon_regmap_lookup_by_pdevname") due to lack
|
|
of users.
|
|
|
|
Thus, we have to maintain it locally.
|
|
|
|
This patch includes a fix due to changes in driver_find_device;
|
|
kernel commit: 92ce7e83b4e5 ("driver_find_device: Unify the match function
|
|
with class_find_device()")
