From 5e40b1c1cc5ae9b949f96d40356afd2a31477365 Mon Sep 17 00:00:00 2001 From: Wei Yongjun Date: Mon, 3 Sep 2012 20:42:27 +0800 Subject: gpio/omap: fix possible memory leak in omap2_gpio_dev_init() pdata and pdata->regs have been allocated in this function and should be freed before leaving it, and in the other error handling cases too. spatch with a semantic match is used to found this problem.
