Subject: [PATCH] mmc: mmc_test: fix missing assignment of 'file' when register debugfs file
From: Ye Bin <yebin10@...wei.com>
Now, 'file' is always NULL. obviously, 'file' is used to store return value of
'debugfs_create_file()'.
Fixes: a04c50aaa916 ("mmc: core: no need to check return value of debugfs_create functions")
