Subject: Input: cyttsp - remove useless checks in cyttsp_probe()
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=aaa60fa7ac66ede814f7ad37a2b3a07b4f784756;p=linux-beck.git

Input: cyttsp - remove useless checks in cyttsp_probe()

This fixes reference-before-check problem; there is no reason to check
if caller passed NULL dev or bus_ops as it is done only by bus-specific
drivers which already do the right thing.
