Use 'time_left' as a variable to make the code obvious and self explaining. Also correct the type of the variable if the original code got it wrong. This is part of a tree-wide series. The rest of the patches can be found here: git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux.git i2c/time_left Because these patches are generated, I audit them before sending. This is why I will send series step by step. Build bot is happy with these patches, though. No functional changes intended.
