Hi "Enrico,
I love your patch! Yet something to improve:
[auto build test ERROR on gpio/for-next]
[also build test ERROR on linux/master linus/master v5.10-rc7 next-20201207]
[If your patch is applied to the wrong git tree, kindly drop us a note.

622e040d577dc8 Michael Witten 2011-07-08 13 I2C (pronounce:
I-squared-C) is a slow serial bus protocol used in
^1da177e4c3f41 Linus Torvalds 2005-04-16 14 many micro controller
applications and developed by Philips. SMBus,
^1da177e4c3f41 Linus Torvalds 2005-04-16 15 or System Management Bus is
a subset of the I2C protocol. More
^1da177e4c3f41 Linus Torvalds 2005-04-16 16 information is contained in
the directory <file:Documentation/i2c/>,
^1da177e4c3f41 Linus Torvalds 2005-04-16 17 especially in the file
called "summary" there.

^1da177e4c3f41 Linus Torvalds 2005-04-16 19 Both I2C and SMBus are
supported here. You will need this for
^1da177e4c3f41 Linus Torvalds 2005-04-16 20 hardware sensors support,
and also for Video For Linux support.
^1da177e4c3f41 Linus Torvalds 2005-04-16 21
^1da177e4c3f41 Linus Torvalds 2005-04-16 22 If you want I2C support,
you should say Y here and also to the
^1da177e4c3f41 Linus Torvalds 2005-04-16 23 specific driver for your
bus adapter(s) below.
^1da177e4c3f41 Linus Torvalds 2005-04-16 24
^1da177e4c3f41 Linus Torvalds 2005-04-16 25 This I2C support can also
be built as a module. If so, the module
^1da177e4c3f41 Linus Torvalds 2005-04-16 26 will be called i2c-core.
