Jean-Philippe Brucker a1e533ec07 fbcon: set a default value to blink interval ... Since commit 27a4c827c3 fbcon: use the cursor blink interval provided by vt two attempts have been made at fixing a possible hang caused by cursor_timer_handler. That function registers a timer to be triggered at "jiffies + fbcon_ops.cur_blink_jiffies". A new case had been encountered during initialisation of clcd-pl11x: fbcon_fb_registered do_fbcon_takeover -> do_register_con_driver fbcon_startup (A) add_cursor_timer (with cur_blink_jiffies = 0) -> do_bind_con_driver visual_init fbcon_init (B) cur_blink_jiffies = msecs_to_jiffies(vc->vc_cur_blink_ms); If we take an softirq anywhere between A and B (and we do), cursor_timer_handler executes indefinitely. Instead of patching all possible paths that lead to this case one at a time, fix the issue at the source and initialise cur_blink_jiffies to 200ms when allocating fbcon_ops. This was its default value before aforesaid commit. fbcon_cursor or fbcon_init will refine this value downstream.
