[PATCH 2/2] staging: rts5208: Remove RTSX_READ_REG and RTSX_WRITE_REG macros

From: Joe Perches
Date: Wed Mar 25 2015 - 15:55:23 EST

Macros with hidden flow control are bad form as the code path
taken can be unexpected for the reader.

Expand these in-place and remove the macros.

Done with coccinelle script:
