Subject: [PATCH] staging: rts5208: Add parenthesis to macro arguments

Checkpatch suggests using (reg) and (host) instead of reg and host

The use of parenthesis in the macro argument '(reg)' ensures proper
precedence and resolves potential issues that may arise due to the
surrounding code context. This modification adheres to the recommended
coding style and improves the readability or maintainability of the
code.
