From e17fd4ba2a81f1d29875b20464e4899185a3c946 Mon Sep 17 00:00:00 2001 From: John Stultz Date: Tue, 31 May 2011 23:26:11 -0700 Subject: rtc: Fix ioctl error path return Bryan Henderson noticed that the "RTC: Fix rtc driver ioctl specific shortcutting" commit has a small bug: When an ioctl is called with an invalid command code and the clock driver does not have an "ioctl" method, the ioctl returns rc 0 instead of -ENOTTY. This patch fixes the issue. CC: Bryan Henderson CC: Gabor Z.
