drm/mgag200: Acquire I/O lock while reading EDID
DDC operation conflicts with concurrent mode setting. Acquire the
driver's I/O lock in get_modes to prevent this. This change should
have been part of commit 931e3f3a0e99 ("drm/mgag200: Protect
concurrent access to I/O registers with lock"), but apparently got
lost somewhere.
v3:
* fix commit message to say 'drm/mgag200' (Jocelyn)
