mmc: core: Use DEFINE_DEBUGFS_ATTRIBUTE instead of DEFINE_SIMPLE_ATTRIBUTE
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") Reported-by: Hulk Robot <hulkci@huawei.com> Signed-off-by: Zou Wei <zou_wei@huawei.com> Link: https://lore.kernel.org/r/1587633319-19835-1-git-send-email-zou_wei@huawei.com Signed-off-by: Ulf Hansson <ulf.hansson@linaro.org>
