Dan Carpenter	d7c2496097	LoongArch: Delete unnecessary debugfs checking ... Debugfs functions are not supposed to be checked for errors. This is sort of unusual but it is described in the comments for the debugfs_create_dir() function. Also debugfs_create_dir() can never return NULL.

Immad Mir	41efbb682d	LoongArch: Fix debugfs_create_dir() error checking ... The debugfs_create_dir() returns ERR_PTR in case of an error and the correct way of checking it is using the IS_ERR_OR_NULL inline function rather than the simple null comparision. This patch fixes the issue.

Huacai Chen	61a6fccc0b	LoongArch: Add unaligned access support ... Loongson-2 series (Loongson-2K500, Loongson-2K1000) don't support unaligned access in hardware, while Loongson-3 series (Loongson-3A5000, Loongson-3C5000) are configurable whether support unaligned access in hardware. This patch add unaligned access emulation for those LoongArch processors without hardware support. Signed-off-by: Huacai Chen <chenhuacai@loongson.cn>	2022-12-14 08:36:11 +08:00
