Subject: mISDN: remove unnecessary test on f_pos
X-Git-Tag: upstream/snapshot3+hdmi~14155
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=b627dbce6b5524c7c9032738bb60538999f45d41;p=platform%2Fadaptation%2Frenesas_rcar%2Frenesas_kernel.git

mISDN: remove unnecessary test on f_pos

This test is not doing anything since it is always false if the
mISDN_read() is called from vfs_read().  Besides that the driver uses
nonseekable_open() and is not using off or file->f_pos anywhere.
