Subject: efi: Remove redundant null pointer checks in efi_debugfs_init()
X-Git-Tag: v6.12-rc1~36^2
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=04736f7d1945722117def1462fd3602c72c02272;p=thirdparty%2Fkernel%2Flinux.git

efi: Remove redundant null pointer checks in efi_debugfs_init()

Since the debugfs_create_dir() never returns a null pointer, checking
the return value for a null pointer is redundant, and using IS_ERR is
safe enough.
