The '==' expression itself is bool, no need to convert it to bool again.
This fixes the following coccicheck warning:
drivers/gpu/drm/amd/display/dc/dcn20/dcn20_mpc.c:455:70-75: WARNING:
conversion to bool not needed here

trivia:
These descriptions are not quite correct.
The operators return an int, either 0 or 1.
-----------------
6.5.8 Relational operators
6 Each of the operators < (less than), > (greater than), <= (less than or equal to), and >=
(greater than or equal to) shall yield 1 if the specified relation is true and 0 if it is false. 90)
The result has type int
6.5.9 Equality operators
3 The == (equal to) and != (not equal to) operators are analogous to the relational
operators except for their lower precedence. 91) Each of the operators yields 1 if the
specified relation is true and 0 if it is false. The result has type int. For any pair of
operands, exactly one of the relations is true.
