X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=d90e6f6aad0ffdc674bc3a05c85c40dcc18e604c;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git

Input: bcm5974 - retract efi-broken suspend_resume

With the recent system-wide improvements on suspend/resume and EFI
booting the suspend_resume method of the bcm5974 has broken. When
waking up from the S3 state on the MacBookAir, the trackpad is found
in a yet unknown state, unable to switch to the proper multitouch
mode. The result is a frozen touchpad, and a flood of errors of the
kind

	bcm5974: bad trackpad package, length: 8.

This patch retracts the reset_resume method altogether, falling back
on the generic unbind/rebind functionality of the usb layer until
further investigations can be made as how to reset the device when
booting from efi.
