Subject: Input: xpad - enable force feedback on xbox 360 controllers only
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=cfbe20106fa00e89c1fb2c74dbff0ba80e0e539d;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

Input: xpad - enable force feedback on xbox 360 controllers only

Commit 4994cd8dadcf9d484ab3ec19f3c7c7a4e5353c1c introduced a
regression which causes xpad to report force feedback cababilities
for non-360 controllers too, even while there is no actual support
for those.

Fix that by adding a check for XTYPE_XBOX360 to xpad_init_ff().
