MIPS: Remove a warning when PHYS_OFFSET is 0x0
Rewrite the comparison in `else if` statement, case where `min_low_pfn > ARCH_PFN_OFFSET` has already been checked in the first `if` statement: if (min_low_pfn > ARCH_PFN_OFFSET) { Fix non-fatal warning during compilation using W=1: arch/mips/kernel/setup.c: In function ‘bootmem_init’: arch/mips/kernel/setup.c:461:25: warning: comparison of unsigned expression < 0 is always false [-Wtype-limits] } else if (min_low_pfn < ARCH_PFN_OFFSET) { ^ Signed-off-by: Mathieu Malaterre <malat@debian.org> Reviewed-by: James Hogan <jhogan@kernel.org> Cc: Ralf Baechle <ralf@linux-mips.org> Cc: linux-mips@linux-mips.org Patchwork: https://patchwork.linux-mips.org/patch/18176/ Signed-off-by: James Hogan <jhogan@kernel.org>
