I wonder if i2c_lock_segment() and i2c_lock_root_adapter() are really
more readable and convenient than i2c_lock_bus() with the flag. I think
the flags have speaking names, too.

Is that an idea to remove these functions altogether and start using
i2c_lock_bus()?

That would be fine with me. I don't have a strong opinion and agree that
both are readable enough...

It would make for a reduction of the number of lines so that's nice, but
the macro in drivers/i2c/busses/i2c-gpio.c (patch 11) would not fit in
the current \-width (or whatever you'd call that line of backslashes to
the right in a multi-line macro).

Does anyone have a strong opinion?

Cheers,
Peter
