media: video: Fix build in saa7164
-tip testing found that the x86 build (64-bit allyesconfig) fails due to: LD vmlinux.o drivers/built-in.o:(.bss+0x4b648): multiple definition of `debug' arch/x86/built-in.o:(.kprobes.text+0x88): first defined here ld: Warning: size of symbol `debug' changed from 90 in arch/x86/built-in.o to 4 in drivers/built-in.o make: *** [vmlinux.o] Error 1 This is because recent saa7164 changes introduced a global symbol named 'debug'. The x86 platform code already defines a 'debug' symbol. (which is named in a too generic way as well - but it can be used nicely to weed out too generic symbols in drivers ;-) Rename it to saa_debug. [mchehab@redhat.com: use module_param_named to preserve old name] Signed-off-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
