MIPS: generic/yamon-dt: fix uninitialized variable error
[ Upstream commit255e51da15
] In the case where fw_getenv returns an error when fetching values for ememsizea and memsize then variable phys_memsize is not assigned a variable and will be uninitialized on a zero check of phys_memsize. Fix this by initializing phys_memsize to zero. Cleans up cppcheck error: arch/mips/generic/yamon-dt.c💯7: error: Uninitialized variable: phys_memsize [uninitvar] Fixes:f41d2430bb
