The correct format is not used and no attempt has been made to document the function arguments. Makes sense to just demote the headers back down to simple comments. Fixes the following W=1 warnings: drivers/misc/mic/host/mic_debugfs.c:108: warning: Function parameter or member 'mdev' not described in 'mic_create_debug_dir' drivers/misc/mic/host/mic_debugfs.c:131: warning: Function parameter or member 'mdev' not described in 'mic_delete_debug_dir' Cc: Sudeep Dutt <sudeep.dutt@intel.com> Cc: Ashutosh Dixit <ashutosh.dixit@intel.com> Signed-off-by: Lee Jones <lee.jones@linaro.org> Link: https://lore.kernel.org/r/20200701083118.45744-15-lee.jones@linaro.org Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
