Can you please comment why you don't apply this series?
My point of view is:
devm_platform_ioremap_resource is the designated wrapper to replace
platform_get_resource() and devm_ioremap_resource(). So I don't see a
good reason to continue open coding it.
The patch series doesn't apply to 5.10-rc1 as is. (pwm-puv3 was removed
and a simple conflict in the pwm-rockchip driver.) The overall diffstat
(of the fixed series applied on top of 5.10-rc1) is
31 files changed, 32 insertions(+), 96 deletions(-)
and it converts all of drivers/pwm but a single instance of
platform_get_resource() + devm_ioremap_resource() (for pwm-lpss where
platform_get_resource and devm_ioremap_resource are in different
functions (different files even)) which isn't trivial to fix.
So in my eyes applying this series is the right thing to do.
Best regards
Uwe
