Subject: [patch 1/8] input: bcm5974: retract efi-broken suspend_resume
Date: Mon, 21 Dec 2009 16:22:55 -0800 [thread overview]
Message-ID: <200912220022.nBM0MtvF005032@imap1.linux-foundation.org> (raw)
From: "Henrik Rydberg" <rydberg@euromail.se>
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.
