[PATCH v4 6/7] i2c: bcm2835: Support i2c-dev ioctl I2C_TIMEOUT

From: Noralf Trønnes <hidden>

Also in: linux-i2c, lkml
Subsystem: i2c subsystem, i2c subsystem host drivers, the rest · Maintainers: Andi Shyti, Linus Torvalds

Use i2c_adapter->timeout for the completion timeout value. The core
default is 1 second.
