Subject: [PATCH v2 0/7] i2c: npcm: Bug fixes read/write operation, checkpatch

This patchset includes the following fixes:

- Restore the npcm_i2caddr array length to fix the smatch warning.
- Enable the target functionality in the interrupt handling routine 
  when the i2c transfer is about to finish.
- Correct the read/write operation procedure.
- Introduce a software flag to handle the bus error (BER) condition
  which is not caused by the i2c transfer.
- Modify timeout calculation.
- Assign the client address earlier logically.
- Use an i2c frequency table for the frequency parameters assignment.
- Coding style fix.

The NPCM I2C driver is tested on NPCM750 and NPCM845 evaluation boards.

- Remove unused variables.
- Handle the condition where scl_table_cnt reaches to the maximum value.
- Fix the checkpatch warning.
