ARM: OMAP2+: GPMC: resolve type-conversion warning from sparse
arch/arm/mach-omap2/gpmc.c passes a return value from ioremap() as the fifth argument to request_irq() without casting it. This causes sparse to generate the following warning: arch/arm/mach-omap2/gpmc.c:759:63: warning: incorrect type in argument 5 (different address spaces) arch/arm/mach-omap2/gpmc.c:759:63: expected void *dev arch/arm/mach-omap2/gpmc.c:759:63: got void [noderef] <asn:2>*static [toplevel] [assigned] gpmc_base It turns out that it's not necessary to pass this. gpmc_base is a file-scoped static variable, the ISR is located in the same file ... and the ISR doesn't even touch the passed-in variable. So, just replace it with NULL in request_irq(). Signed-off-by: Paul Walmsley <paul@pwsan.com>
