From df2e268226e2e3d79980a5dddfd683126f79ddb4 Mon Sep 17 00:00:00 2001 From: Lars-Peter Clausen Date: Thu, 16 Jul 2015 21:22:49 +0200 Subject: [PATCH] ASoC: max9877: Make driver global regmap struct local Use a stack local variable to handle function local state rather than a global static variable. The later has a potential for race conditions if the probe function runs for two devices concurrently.
