From: Stefan Richter Date: Sat, 1 Mar 2008 11:34:50 +0000 (+0100) Subject: firewire: fw-ohci: switch on bus power after resume on PPC PMac X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=eb5ca72effaa7f691f7df5187c5c5d1268311326;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git firewire: fw-ohci: switch on bus power after resume on PPC PMac The platform feature calls in the suspend method switched off cable power, but the calls in the resume method did not switch it back on. Add the necessary feature call to .resume. Also add the corresponding call to .suspend to make .suspend's behavior explicitly the same on all PMacs.
