From b64da05fb746c6ff5bcb9abeaa52684d1b08a2b9 Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Tue, 19 Nov 2013 13:28:06 -0800 Subject: [PATCH] Input: hp_sdc_rtc - unlock on error in hp_sdc_rtc_read_i8042timer() The transaction task here is hp_sdc_tasklet() and it releases the lock. The problem is if we aren't able to queue the transaction then we need to release the lock ourselves.
