From 70e176a5a9839ea22f0fbcfa21d1c8ae952a0dd2 Mon Sep 17 00:00:00 2001 From: Guennadi Liakhovetski Date: Fri, 21 Dec 2012 10:28:43 -0300 Subject: [PATCH] [media] soc-camera: use devm_kzalloc in subdevice drivers I2C drivers can use devm_kzalloc() too in their .probe() methods. Doing so simplifies their clean up paths.
