MIPS: Loongson: Fix potential NULL dereference in loongson3_platform_init()
[ Upstream commit 72d052e28d1d2363f9107be63ef3a3afdea6143c ]
If kzalloc fails, it should return -ENOMEM, otherwise may trigger a NULL
pointer dereference.
Fixes: 3adeb2566b9b ("MIPS: Loongson: Improve LEFI firmware interface")
