Subject: [PATCH 3/5] backlight: ld9040: replace EFAULT with EINVAL
Date: Thu, 20 Dec 2012 15:38:15 +0900 [thread overview]
Message-ID: <001101cdde7c$96cb4fb0$c461ef10$%han@samsung.com> (raw)
In-Reply-To: <000f01cdde7c$5d4e83b0$17eb8b10$%han@samsung.com>
This patch replaces EFAULT with EINVAL, because EFAULT tends to be
for the invalid memory addresses.
