Subject: [PATCH 6/8] misc: eeprom: at24: clean up at24_bin_write()
Date: Mon, 27 Jul 2015 00:18:51 +0300 [thread overview]
Message-ID: <1437945533-27996-6-git-send-email-vz@mleia.com> (raw)
In-Reply-To: <1437945502-27944-1-git-send-email-vz-ChpfBGZJDbMAvxtiuMwx3w@public.gmane.org>
The change removes redundant sysfs binary file boundary check, since
this task is already done on caller side in fs/sysfs/file.c
