Subject: Re: [PATCH] input: synaptics_i2c - cancel delayed work before freeing device

Hi Dmitry,

Thanks for the review.

Understood that cancel_delayed_work_sync() is already called from the
close() handler, and that resume() can restart polling regardless of
open state. If we keep this driver, I can send a v2 that adds an open-state
guard in resume().

However, if this driver is no longer used and Mike confirms there are no
remaining users, I have no objections to removing it instead.

Thanks,
Minseong
