Subject: [PATCH 1/3] i2c-s3c2410: Convert to devm_kzalloc()
Date: Mon, 13 Feb 2012 15:05:02 -0800 [thread overview]
Message-ID: <1329174304-12228-1-git-send-email-broonie@opensource.wolfsonmicro.com> (raw)
Saves remembering to call kfree(). There's some kfree()s used by the
resource still, these will be removed in 3.4 using the newly added
devm_request_and_ioremap().
