Subject: [PATCH] rsxx: Remove unnecessary parentheses

Clang warns when more than one set of parentheses is used for a
single conditional statement:

drivers/block/rsxx/cregs.c:279:15: warning: equality comparison with
extraneous parentheses [-Wparentheses-equality]
if ((cmd->op == CREG_OP_READ)) {
~~~~~~~~^~~~~~~~~~~~~~~
drivers/block/rsxx/cregs.c:279:15: note: remove extraneous parentheses
around the comparison to silence this warning
if ((cmd->op == CREG_OP_READ)) {
~ ^ ~
drivers/block/rsxx/cregs.c:279:15: note: use '=' to turn this equality
comparison into an assignment
if ((cmd->op == CREG_OP_READ)) {
^~
=
1 warning generated.
