MIPS: generic/yamon-dt: fix uninitialized variable error
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:100:7: error: Uninitialized variable: phys_memsize [uninitvar] Fixes: f41d2430bbd6 ("MIPS: generic/yamon-dt: Support > 256MB of RAM") Signed-off-by: Colin Ian King <colin.i.king@gmail.com> Signed-off-by: Thomas Bogendoerfer <tsbogend@alpha.franken.de>
