Subject: e1000e: Switch e1000e_up to void, drop code checking for error result
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=386164d9b36b1f6f1396978110de85c7e186491d;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

e1000e: Switch e1000e_up to void, drop code checking for error result

The function e1000e_up always returns 0.  As such we can convert it to a
void and just ignore the results.  This allows us to drop some code in a
couple spots as we no longer need to worry about non-zero return values.
