Subject: [PATCH AUTOSEL 4.9 32/66] media: davinci: Fix implicit enum conversion warning

From: Nathan Chancellor <natechancellor@...il.com>

[ Upstream commit 4158757395b300b6eb308fc20b96d1d231484413 ]

Clang warns when one enumerated type is implicitly converted to another.

drivers/media/platform/davinci/vpbe_display.c:524:24: warning: implicit
conversion from enumeration type 'enum osd_v_exp_ratio' to different
enumeration type 'enum osd_h_exp_ratio' [-Wenum-conversion]
                        layer_info->h_exp = V_EXP_6_OVER_5;
                                          ~ ^~~~~~~~~~~~~~
1 warning generated.

This appears to be a copy and paste error judging from the couple of
lines directly above this statement and the way that height is handled
in the if block above this one.
