Subject: i2c: synquacer: use 'time_left' variable with wait_for_completion_timeout()
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=4259964b4a5299cb4fb9f5e06dccafb2ae05cb20;p=linux.git

i2c: synquacer: 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.
