From: Ramiro Oliveira <Ramiro.Oliveira@xxxxxxxxxxxx> commit bb475230b8e59a547ab66ac3b02572df21a580e9 upstream. The *_get_optional_* functions weren't really optional so this patch makes them really optional. These *_get_optional_* functions will now return NULL instead of an error if no matching reset phandle is found in the DT, and all the reset_control_* functions now accept NULL rstc pointers. Signed-off-by: Ramiro Oliveira <Ramiro.Oliveira@xxxxxxxxxxxx> Signed-off-by: Philipp Zabel <p.zabel@xxxxxxxxxxxxxx> --- Please apply to v4.9.y stable tree.
The original commit had a few upstream fixes: bb6c7768385b reset: remove remaining WARN_ON() in <linux/reset.h> 1554bbd4ad40 reset: make device_reset_optional() really optional 62e24c5775ec reset: add exported __reset_control_get, return NULL if optional 0ca10b60ceeb reset: fix optional reset_control_get stubs to return NULL 4891486fb2c8 reset: core: fix reset_control_put We'll need to backport them to 4.9 as well if you backport this commit. -- Thanks, Sasha
