[PATCH 3.18 47/68] staging: imx-drm: fix indentation warning

[Greg Kroah-Hartman]

3.18-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Arnd Bergmann <arnd@xxxxxxxx>

gcc-6 produces a harmless warning:

drivers/staging/imx-drm/imx-hdmi.c: In function 'hdmi_config_AVI':
drivers/staging/imx-drm/imx-hdmi.c:967:2: error: this 'else' clause does not guard... [-Werror=misleading-indentation]

Commit d083c312cba2 ("drm: bridge/dw_hdmi: simplify hdmi_config_AVI() a little")
in linux-4.3 fixes this with a larger rewrite that is not applicable here.
After that rewrite, the variable that gets assigned here no longer exists.

The assignment is rather pointless here, as we just set a variable to zero
that is later added into another variable using a bitwise or operator, and
that has no effect, so I'm just changing the indentation here to shut up
the warning.

The driver was originally merged in linux-3.13, and the fix applies
to all versions between that and 4.2.
