[PATCH 1/2] mtd: nand: mxc_nand: use 'time_left' variable with wait_for_completion_timeout()

From: Wolfram Sang
Date: Tue Jun 04 2024 - 17:30:17 EST


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.
