Merge branch 'i2c/cht-wc-fusb302-immutable' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux
Pull i2c/cht-wc-fusb302-immutable immutable branch from Wolfram Sang:
as discussed before, here is the immutable branch for the i2c-cht-wc
driver, so you can safely apply Hans' patch [1]
"platform/x86: intel_cht_int33fe: Update fusb302 type string, add properties"
on top of this.
