This creates a time window during which hot plug detection interrupts can occur with an encoder, resulting in a crash in the IRQ handler. Fix this by ignoring hot plug detection IRQs when no encoder is associated yet.

This allows DRM to supply proper aspect ratio information derived from the DRM display mode structure.

This ensure that the regmap cache is properly marked as dirty when the device is probed, and the registers properly synced during the first power up. As a side effect this removes the initialization of current_edid_segment at probe time, as the field will be initialized when the device is powered on, at the latest right before reading EDID data.

The condition passed to the macro reads I2C registers. This results in sleeping with the task state set to TASK_INTERRUPTIBLE, triggering a WARN_ON() introduced in commit 8eb23b9f35aae ("sched: Debug nested sleeps"). Fix this by reworking the EDID read code. Instead of checking whether the read is complete through I2C reads, handle the interrupt registers in the interrupt handler and update a new edid_read flag accordingly. As a side effect both the IRQ and polling code paths now process the interrupt sources through the same code path, simplifying the code.
