[Intel-gfx] [PATCH] drm/i915: Build request info on stack before printk

[Chris Wilson]

Quoting Chris Wilson (2018-04-24 02:08:39)
> printk unhelpfully inserts a '\n' between consecutive calls, and since
> our drm_printf wrapper may be emitting info a seq_file instead,
> KERN_CONT is not an option. To work with any drm_printf destination, we
> need to build up the output into a temporary buf on the stack and then
> feed the complete line in a single call to printk.
