[PATCH] USB: ehci/mxc: compile fix

From: Uwe Kleine-KÃnig
Date: Fri Oct 29 2010 - 03:38:10 EST


65fd42724aee31018b0bb53f4cb04971423be664 broke the build using
ARM's mx51_defconfig:

CC drivers/usb/host/ehci-hcd.o
In file included from drivers/usb/host/ehci-hcd.c:1166:
drivers/usb/host/ehci-mxc.c: In function 'ehci_mxc_drv_probe':
drivers/usb/host/ehci-mxc.c:192: error: 'ehci' undeclared (first use in this function)
drivers/usb/host/ehci-mxc.c:192: error: (Each undeclared identifier is reported only once
drivers/usb/host/ehci-mxc.c:192: error: for each function it appears in.)
drivers/usb/host/ehci-mxc.c:117: warning: unused variable 'temp'
make[3]: *** [drivers/usb/host/ehci-hcd.o] Error 1
make[2]: *** [drivers/usb/host/ehci-hcd.o] Error 2
make[1]: *** [sub-make] Error 2
make: *** [all] Error 2

Fix it together with the warnung about the unused variable.
