drivers/net/wireless/mediatek/mt76/debugfs.c:36:0-23: WARNING: fops_regval should be defined with DEFINE_DEBUGFS_ATTRIBUTE
Use DEFINE_DEBUGFS_ATTRIBUTE rather than DEFINE_SIMPLE_ATTRIBUTE
for debugfs files.
Semantic patch information:
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: a5f6039c8f9c ("mt76: add driver code for MT76x2e")
