Staging: rts5208: helper function to manage aspm during reset
Define the helper function rtsx_reset_aspm to shorten the rtsx_reset_chip code and get rid of the LONG_LINE checkpatch warnings. Signed-off-by: Fabio Falzoi <fabio.falzoi84@gmail.com> Reviewed-by: Dan Carpenter <dan.carpente@oracle.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
