Subject: Staging: ipack: reset previous timeouts during device registration.
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=8a3ae16e60fb78e0bf062c243ffba5575b64a412;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

Staging: ipack: reset previous timeouts during device registration.

Resetting the previous timeout we avoid to read the timeout status register
and see timeout errors that don't correspond to the present state of the
device.
