Subject[PATCH 5.4 290/314] drm/amd/display: Use swap() where appropriate
Date
From: Ville Syrjälä <ville.syrjala@linux.intel.com>

[ Upstream commit 34b86b75dfc90ab3d996c224314ce51772a3b351 ]

Mostly a cocci-job, but it flat out refused to remove the
declaration in drivers/gpu/drm/amd/display/dc/core/dc.c so
had to do that part manually.

@swap@
identifier TEMP;
expression A,B;
@@
- TEMP = A;
- A = B;
- B = TEMP;
+ swap(A, B);

@@
type T;
identifier swap.TEMP;
@@
(
- T TEMP;
|
- T TEMP = {...};
)
... when != TEMP
