14 years agodrm: Prefix info printk about registering panic notifier with 'drm'

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)

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.)

This patch is basically a clean up, because timings[] is declared inside
a union and increasing the number of elements here doesn't change the
overall size of the union.

Multifunction SDVO cards stopped working after 14571b4, and would report
something that looked remarkably like an ADD2 SPD ROM instead of EDID.
This appears to be because DDC bus selection was utterly horked by that
commit; controlled_output was no longer always a single bit, so
intel_sdvo_select_ddc_bus would pick bus 0, which is (unsurprisingly)
the SPD ROM bus, not a DDC bus.

So, instead of that, let's just use the DDC bus the child device table
tells us to use.  I'm guessing at the bitmask and shifting from VBIOS
dumps, but it can't possibly be worse.
