ARC: uaccess: dont use "l" gcc inline asm constraint modifier
commitsteinar/wifi_calib_4_9_kernel79435ac78d
upstream. This used to setup the LP_COUNT register automatically, but now has been removed. There was an earlier fix3c7c7a2fc8
which fixed instance in delay.h but somehow missed this one as gcc change had not made its way into production toolchains and was not pedantic as it is now ! Signed-off-by: Vineet Gupta <vgupta@synopsys.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
