Date: Wed, 25 Nov 2015 13:52:02 +0100 From: LABBE Corentin <clabbe.montjoie@...il.com> To: mturquette@...libre.com, sboyd@...eaurora.org Cc: LABBE Corentin <clabbe.montjoie@...il.com>, linux-clk@...r.kernel.org, linux-kernel@...r.kernel.org Subject: [PATCH 2/2] clk: palmas: fix a possible NULL dereference of_match_device could return NULL, and so cause a NULL pointer dereference later. Even if the probability of this case is very low, fixing it made static analyzers happy. Solving this with of_device_get_match_data made also code simplier.
