Public bug reported:
SRU Justification
[Impact]
The timeout value in i2c-designware is hardcoded. Userspace tool may want to
change the timeout value via ioctl I2C_TIMEOUT, but it doesn't work for
i2c-designware.
[Test Case]
Change the timeout value via ioctl I2C_TIMEOUT. Nothing happened.
With the patch, timeout value for i2c-designware will be updated correctly.
[Regression Potential]
Minimal. The change only applies to a specific driver, i2c-designware. Also, it
has minimal code change.
