[PATCH 0/6] drm: remove redundant else across drivers

[Aditya Garg]

In primary_plane_helper_atomic_check of various drm drivers, a redundant
else statement is there. All these statements match this pattern:

if (foo)
	return foo;
else if (bar)
	return bar;

Which is equivalent to:

if (foo)
	return foo;

if (bar)
	return bar;

This error was observed by Andy Shevchenko [1] while reviewing the
appletbdrm driver, which has been submitted upstream.

A simple grep was used to find such errors.

Most likely a common code was copied and pasted among these drivers.
Some of them also seem to have been ported to use atomic helpers instead
of simple_display_pipe.
