Use 'time_left' as a variable to make the code obvious and self explaining. This is part of a tree-wide series. The rest of the patches can be found here (some parts may still be WIP): 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. Changes since v1: * tags added (thanks!) * white space issue in sun6i driver fixed * add maintainers to coverletter Wolfram Sang (8): spi: armada-3700: use 'time_left' variable with wait_for_completion_timeout() spi: fsl-lpspi: use 'time_left' variable with wait_for_completion_timeout() spi: imx: use 'time_left' variable with wait_for_completion_timeout() spi: pic32-sqi: use 'time_left' variable with wait_for_completion_timeout() spi: pic32: use 'time_left' variable with wait_for_completion_timeout() spi: sun4i: use 'time_left' variable with wait_for_completion_timeout() spi: sun6i: use 'time_left' variable with wait_for_completion_timeout() spi: xlp: use 'time_left' variable with wait_for_completion_timeout() drivers/spi/spi-armada-3700.c | 8 ++++---- drivers/spi/spi-fsl-lpspi.c | 14 +++++++------- drivers/spi/spi-imx.c | 20 ++++++++++---------- drivers/spi/spi-pic32-sqi.c | 6 +++--- drivers/spi/spi-pic32.c | 6 +++--- drivers/spi/spi-sun4i.c | 9 +++++---- drivers/spi/spi-sun6i.c | 17 +++++++++-------- drivers/spi/spi-xlp.c | 8 ++++---- 8 files changed, 45 insertions(+), 43 deletions(-)
