Subject: [PATCH] mmc: core: Use DEFINE_DEBUGFS_ATTRIBUTE instead of DEFINE_SIMPLE_ATTRIBUTE
Git-commit: 43170255321f83d8e8a3964f70040c49b3d19df0
Patch-mainline: v5.8-rc1
References: git-fixes
Fixes coccicheck warning:
drivers/mmc/core/debugfs.c:222:0-23: WARNING: mmc_clock_fops should be
defined with DEFINE_DEBUGFS_ATTRIBUTE
Use DEFINE_DEBUGFS_ATTRIBUTE rather than DEFINE_SIMPLE_ATTRIBUTE
for debugfs files
Fixes: 703aae3d09a4b ("mmc: add a file to debugfs for changing host clock at runtime")
Fixes: a04c50aaa916f ("mmc: core: no need to check return value of debugfs_create functions")
