[PATCH] mhi_bus: dev: netdev: fix debugfs_simple_attr.cocci warnings

[PATCH] mhi_bus: dev: netdev: fix debugfs_simple_attr.cocci warnings

[Julia Lawall]

From: Fengguang Wu <fengguang.wu@intel.com>

 Use DEFINE_DEBUGFS_ATTRIBUTE rather than DEFINE_SIMPLE_ATTRIBUTE
 for debugfs files.

 Rationale: DEFINE_SIMPLE_ATTRIBUTE + debugfs_create_file()
 imposes some significant overhead as compared to
 DEFINE_DEBUGFS_ATTRIBUTE + debugfs_create_file_unsafe().

Generated by: scripts/coccinelle/api/debugfs/debugfs_simple_attr.cocci

Fixes: e693c860afd8 ("mhi_bus: dev: netdev: add network interface driver")
