MIPS: Remove invalid check
Unsigned values cannot be lesser than zero. The problem has been detected using proposed semantic patch scripts/coccinelle/tests/unsigned_lesser_than_zero.cocci [1]. [ralf@linux-mips.org: Chris Dearman's original commit 9318c51acd9689505850152cc98277a6d6f2d752 ([MIPS] MIPS32/MIPS64 secondary cache management) introduced these less than zero checks in 2.6.18.] [1]: http://permalink.gmane.org/gmane.linux.kernel/2038576 Signed-off-by: Andrzej Hajda <a.hajda@samsung.com> Cc: linux-kernel@vger.kernel.org Cc: Bartlomiej Zolnierkiewicz <b.zolnierkie@samsung.com> Cc: Marek Szyprowski <m.szyprowski@samsung.com> Cc: Markos Chandras <markos.chandras@imgtec.com> Cc: Chris Dearman <chris.dearman@imgtec.com> Cc: linux-mips@linux-mips.org Patchwork: https://patchwork.linux-mips.org/patch/11165/ Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
