Quentin Lambert 11201769d1 staging: rts5208: Convert variable from int to bool and propagate the change to function parameters 
This patch convert local variables declared as int into booleans.
It also propagates the conversion when these variables were used
as function parameters.

Coccinelle was used to generate this patch.
