Subject: [PATCH AUTOSEL 4.19 2/6] MIPS: Fix a compilation issue

From: xurui <xurui@...inos.cn>

[ Upstream commit 109d587a4b4d7ccca2200ab1f808f43ae23e2585 ]

arch/mips/include/asm/mach-rc32434/pci.h:377:
cc1: error: result of ‘-117440512 << 16’ requires 44 bits to represent, but ‘int’ only has 32 bits [-Werror=shift-overflow=]

All bits in KORINA_STAT are already at the correct position, so there is
no addtional shift needed.
