Merge branch 'i2c/for-current' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux
Pull i2c bugfixes from Wolfram Sang: "These should have been in rc2 but I missed it due to working on devm longer than expected. There is one ID addition, since we are touching the driver anyhow. And the feature bit documentation is one outcome of a debug session and will make it easier for users to work around problems. The rest is typical driver bugfixes." * 'i2c/for-current' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux: i2c: suppress lockdep warning on delete_device i2c: mv64xxx: work around signals causing I2C transactions to be aborted i2c: i801: Document feature bits in modinfo i2c: designware: add Intel BayTrail ACPI ID i2c: designware: always clear interrupts before enabling them i2c: designware: fix RX FIFO overrun
