i2c: stm32f7: use 'time_left' variable with wait_for_completion_timeout()
There is a confusing pattern in the kernel to use a variable named 'timeout' to store the result of wait_for_completion_timeout() 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. Signed-off-by: Wolfram Sang <wsa+renesas@sang-engineering.com> Signed-off-by: Andi Shyti <andi.shyti@kernel.org>
