[PATCH v2 0/3] Input: raydium_i2c_ts report handling fixes

[Pooyan Azad]

Hi Dmitry,

This is v2 of the Raydium report parameter patch, split as requested.

Patch 1 validates the packet and contact sizes supplied by the controller.
It also propagates main firmware query errors because otherwise a validation
failure would be ignored by initialization. This is the only patch marked
for stable.

Patch 2 resizes an existing report buffer when a firmware update changes the
packet size. Patch 3 moves the initial allocation to the main firmware query
so devices can remain usable for recovery when they probe in bootloader mode.

Changes in v2:
- Split validation, buffer resizing, and bootloader-mode allocation handling
  into separate patches.
- Mark only the validation fix for stable.
- Rebase onto v7.3-rc5.

The series was compile-tested with:

  make O=/tmp/raydium-build W=1 -j$(nproc) \
       drivers/input/touchscreen/raydium_i2c_ts.o

No runtime testing with a Raydium controller was performed.

Thanks,
Pooyan
