This patch is breaking the build at following location in
(arch/arm/mach-omap2/usb-musb.c)
#ifdef CONFIG_USB_MUSB_SOC
static struct resource musb_resources[] = {
[0] = {
.start = cpu_is_omap34xx()
? OMAP34XX_HSUSB_OTG_BASE
: OMAP243X_HS_BASE,
.end = cpu_is_omap34xx()
? OMAP34XX_HSUSB_OTG_BASE + SZ_8K - 1
: OMAP243X_HS_BASE + SZ_8K -1,
.flags = IORESOURCE_MEM,
},
Here, cpu_is_omap34xx() is expected to be evaluated as constant by the
compiler, but my earlier patch was eveluating as inline function causing the
build to fail.
Did not catch is earlier as CONFIG_USB_MUSB_SOC was not set in my .config :(
I will be re-submitting this patch again.
