[PATCH AUTOSEL 4.14 2/5] ASoC: max98090: Reject invalid values in custom control put()
by Sasha Levin 10 May '22

10 May '22

From: Mark Brown <broonie(a)kernel.org> [ Upstream commit 2fbe467bcbfc760a08f08475eea6bbd4c2874319 ] The max98090 driver has a custom put function for some controls which can only be updated in certain circumstances which makes no effort to validate that input is suitable for the control, allowing out of spec values to be written to the hardware and presented to userspace. Fix this by returning an error when invalid values are written.
