drm: Prefix info printk about registering panic notifier with 'drm'
Recently I've studied my system dmesg and seen this:
<lots of stuff before>
1 [ 0.478416] ACPI: Battery Slot [C1B4] (battery present)
2 [ 0.478648] ACPI: Battery Slot [C1B3] (battery absent)
3 [ 0.906678] [drm] initialized overlay support
4 [ 1.762304] Console: switching to colour frame buffer device 128x48
5 [ 1.765211] fb0: inteldrmfb frame buffer device
6 [ 1.765242] registered panic notifier
7 [ 1.765272] [drm] Initialized i915 1.6.0 20080730 for 0000:00:02.0 on minor 0
8 [ 1.765372] Serial: 8250/16550 driver, 4 ports, IRQ sharing enabled
<lots of stuff after>
and it was not evident who registered that panic notifier on line 6.
I'd bought it as some low-level stuff needed by kernel itself, but the
time was inappropriate -- too late for such things.
So I had to study sources to see it was drm who was registering
switch-to-fb on panic.
Let's avoid possible confusion and mark this message as going from drm
subsystem.
(I'm a bit unsure whether to use '[drm]:' or 'drm:' -- the rest of the
kernel just uses 'topic:', and even in drm_fb_helper.c we use 'fb%d:'
without [] brackets. Either way is ok with me.)
