[PATCH V2 0/2] i2c: imx: Fix block read handling for invalid length

This series fixes a crash and bus lockup when SMBus block read operations
encounter invalid length values (zero or greater than I2C_SMBUS_BLOCK_MAX).

Both patches have been tested on i.MX 8M Plus with continuous block read
operations from battery and keyboard devices sharing the same I2C bus.

Changes in v2:
  - Split into two patches for clearer separation of concerns
  - Add detailed comments with reference manual citations
  - Implement abort handling in a dedicated ISR state and handler function
  - Remove modifications to i2c_imx_stop() to avoid affecting normal stop

LI Qingwu (2):
  i2c: imx: preserve error state in block data length handler
  i2c: imx: add abort path for invalid block length
