Subject: [PATCH v4 16/18] staging: r8188eu: hal: Clean up rtw_read*() and rtw_write*()
Clean up rtw_read{8,16,32}() and rtw_write{8,16,32,N}() in usb_ops_linux.c
because some of their code will be reused in the following two patches of
this series. This cleanup is in preparation for shortening the call chains
of rtw_read{8,16,32}() and rtw_write{8,16,32,N}().
