Subject: Input: wacom - check for allocation failure in probe()
X-Git-Tag: accepted/tizen/common/20141203.182822~153^2~155
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=f182394033d639679264d61e6dca62761e659ff7;p=platform%2Fkernel%2Flinux-arm64.git

Input: wacom - check for allocation failure in probe()

We accidentally removed the check for NULL in 3aac0ef10b "Input: wacom -
isolate input registration".
