Subject: [PATCH v2] staging: rtl8712: Move similar execution in to a function.
Message-ID: <YTsXXxtQn7QN6nIm@user>
MIME-Version: 1.0
Content-Type: text/plain; charset=us-ascii
Content-Disposition: inline
Precedence: bulk

In rtl8712_cmd.c function read_macreg_hdl,write_macreg_hdl,write_bbreg_hdl
and write_rfreg_hdl all are having same execution.

Move this common execution in to a new function common_read_write_hdl().
Call common_read_write_hdl() from read_macreg_hdl,write_macreg_hdl,
write_bbreg_hdlhis and write_rfreg_hdl.This will reduce duplicate code.
