[PATCH 1/2] qd65xx: always use ->selectproc method

From: Bartlomiej Zolnierkiewicz
Date: Sat Feb 23 2008 - 13:58:58 EST


qd_select() checks itself whether timings should be reprogrammed so
remove superfluous qd_timing_ok() and always use ->selectproc method
(rename qd_select() to qd65xx_select() while at it).
