Subject: [PATCH 00/15] i2c: use 'time_left' with wait_for_*
Date: Sat, 27 Apr 2024 22:35:52 +0200

There is a confusing pattern in the kernel to use a variable named 'timeout' to
store the result of wait_for_*() causing patterns like:

        timeout = wait_for_completion_timeout(...)
        if (!timeout) return -ETIMEDOUT;

with all kinds of permutations. Use 'time_left' as a variable to make the code
self explaining.

This is the I2C part of a tree-wide series. The rest of the patches can
be found here (slightly WIP):

git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux.git i2c/time_left

Because these patches are generated, they need manual audit. So, I will
send them step by step. This is part 1 and also a call for opinions if
this is a desirable change. But at least in the I2C realm, I really want
to have it proper.

Build bot is happy with these patches and I also compile tested them
(except two). No functional changes intended.
