Subject: [PATCH] spi: remove return value check of debugfs_create_dir()
Date: Sun, 23 Apr 2023 14:11:54 +0800 [thread overview]
Message-ID: <20230423061155.2540-1-ysxu@hust.edu.cn> (raw)
Smatch complains that:
dw_spi_debugfs_init() warn: 'dws->debugfs' is an error pointer
or valid
Debugfs checks are generally not supposed to be checked for errors
and it is not necessary here.
Just delete the dead code.
