[PATCH] drm: bridge: rename the function drm_bridge_hpd_notify to drm_bridge_hpd_cb
by Dafna Hirschfeld 07 Apr '21

07 Apr '21

drm_bridge_funcs has a function called 'hpd_notify'. The function drm_bridge_hpd_notify does not call 'hpd_notify' but it calls 'hpd_cb'. This is rather confusing. Rename the function to fix this confusion.
