Userspace tool may\nwant to change the timeout value via ioctl I2C_TIMEOUT, but it doesn't\nwork for i2c-designware.\n\n[Test Case]\nChange the timeout value via ioctl I2C_TIMEOUT. Nothing happened.\nWith the patch, timeout value for i2c-designware will be updated\ncorrectly.\n\n[Fix]\nThe timeout value now uses adap->timeout instead of hardcoded HZ.\n\n[Regression Potential]\nMinimal. The change only applies to a specific driver, i2c-designware.\nAlso, it has minimal code change.\n\nWeifeng Voon (1):\n i2c: designware: Use transfer timeout from ioctl I2C_TIMEOUT\n\n drivers/i2c/busses/i2c-designware-core.c | 2 +-\n 1 file changed, 1 insertion(+), 1 deletion(-)" }
