usb: host: r8a66597-hcd: Remove set, then over-written, but never used variable 'tmp'
Looks like it's been this way since the driver's inception in 2007.
Fixes the following W=1 kernel build warning(s):
drivers/usb/host/r8a66597-hcd.c: In function ‘clear_all_buffer’:
drivers/usb/host/r8a66597-hcd.c:478:6: warning: variable ‘tmp’ set but not used [-Wunused-but-set-variable]
478 | u16 tmp;
