[PATCH V3 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 v3:
- Add trailing comma to IMX_I2C_STATE_READ_BLOCK_DATA_ABORT enum
- Clean up reference manual citations

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