Subject: platform/x86: ideapad-laptop: hide unused 'touchpad_store'
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=46936fd65c107ed935e21bfa6fc00b4f510b1714;p=linux.git

platform/x86: ideapad-laptop: hide unused 'touchpad_store'

A readonly sysfs property must not have a 'store' function:

drivers/platform/x86/ideapad-laptop.c:438:16: error: 'touchpad_store' defined but not used [-Werror=unused-function]

We can either comment it out or remove the function entirely,
without a good reason one or or another I picked the second option.
