drivers/rapidio/devices/tsi721.c: make module parameter variable name unique
kbuild test robot reported a non-static variable name collision between a staging driver and a RapidIO driver, with a generic variable name of 'dbg_level'. Both drivers should be changed so that they don't use this generic public variable name. This patch fixes the RapidIO driver but does not change the user interface (name) for the module parameter. drivers/staging/built-in.o:(.bss+0x109d0): multiple definition of `dbg_level' drivers/rapidio/built-in.o:(.bss+0x16c): first defined here Link: http://lkml.kernel.org/r/ab527fc5-aa3c-4b07-5d48-eef5de703192@infradead.org Signed-off-by: Randy Dunlap <rdunlap@infradead.org> Reported-by: kbuild test robot <fengguang.wu@intel.com> Cc: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Cc: Matt Porter <mporter@kernel.crashing.org> Cc: Alexandre Bounine <alexandre.bounine@idt.com> Cc: Jérémy Lefaure <jeremy.lefaure@lse.epita.fr> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
