[PATCH] mmc: mmc_test: fix missing assignment of 'file' when register debugfs file

From: Ye Bin
Date: Wed Nov 23 2022 - 04:37:19 EST


From: Ye Bin <yebin10@xxxxxxxxxx>

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")
