[PATCH 0/2] drm/mediatek: HDMI DDC v2 driver fixes

[Louis-Alexis Eyraud]

This patch series fixes two issues in the Mediatek HDMI DDC v2
driver (mtk_hdmi_ddc_v2).

Patch 1 fixes a potential issue on transfer timeout cases to properly
abort read/write transfers.
Patch 2 fixes DDC communication errors that occur when getting
or modifying display features with ddcutil with subcommands such as
detect, getvcp or setvcp:
```
$ ddcutil getvcp 10 -b 4 # read brightness
DDC communication failed for monitor on bus /dev/i2c-4

$ ddcutil setvcp 10 75 -b 4 # change brightness
DDC communication failed for monitor on bus /dev/i2c-4
```

These patches were tested on Mediatek Genio 510-EVK and 1200-EVK boards
with a kernel based on next-20251205 tag plus devicetree patches to
enable HDMI output.
