Hi Dmitry,

You never shared your thoughts about this simplification. Some of
these could be redundant with Rob's work:
https://lore.kernel.org/lkml/CAL_Jsq+ajm5aiAJfQdS2+2DO1ynBDHWha_7TsA4u-2qwd87y6g@mail.gmail.com/
but I am not sure if it was merged.

On the other hand there are here also few other changes like:
>   gpio: Add devm_fwnode_gpiod_get_optional() helpers
>   Input: gpio_keys - Simplify with dev_err_probe()
which does:
8 insertions(+), 17 deletions(-)

and these:
>   Input: bu21013_ts - Use local 'client->dev' variable in probe()
>   Input: bu21029_ts - Use local 'client->dev' variable in probe()

Any comments?

Best regards,
Krzysztof
