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.

LoongArch: Fix debugfs_create_dir() error checking2023-06-15T06:35:56ZImmad Mir2023-06-15T06:35:56Zurn:sha1:41efbb682de1231c3f6361039f46ad149e3ff5b9
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.

LoongArch: Add unaligned access support2022-12-14T00:36:11ZHuacai Chen2022-12-10T14:39:59Zurn:sha1:61a6fccc0bd2e8030b2672a52ef3f6706b2b2ee4
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.
