From 18b548ca580838a2cc5813a941e6dab28660bb22 Mon Sep 17 00:00:00 2001 From: Jean Delvare Date: Tue, 17 Jul 2007 18:29:41 -0300 Subject: [PATCH] V4L/DVB (5884): zr36067: clean up debug function Debugging cleanups to the zr36067 driver: * Use module_param_named() to declare the debug parameter, so we can use a single global variable to handle the debug level. This makes the driver a bit smaller (by 648 bytes on x86_64), thanks to one less level of indirection on every use. * Change the debug parameter sysfs permissions, so that the debug level can be adjusted at runtime, as is done in many other media/video drivers. * The debug level is between 0 and 5, not 0 and 4. * Move the zr_debug export and dprintk macro definition to a header file so that we don't have to define them in each source file. * Simplify a duplicate test on zr_debug. Note that zr_debug was subsequently renamed to debug_zr36067 to avoid possible conflicts with other Zoran device drivers, on a suggestion by Trent Piepho.
