[Intel-wired-lan] [PATCH] ice: Use common error handling code in two functions

[Markus Elfring]

From: Markus Elfring <elfring@users.sourceforge.net>

Add jump targets so that a bit of exception handling can be better reused
at the end of two function implementations.

This issue was detected by using the Coccinelle software.

Thank you for contribution, the change is fine, but not as a bugfix.
Please send as a [iwl-next], when the submission window opens.

Thanks for this positive feedback.

Would you like to qualify my update suggestion as a correction for
a coding style issue?

Will a patch resend really be needed for the proposed adjustment?

Markus

It can go to -next to correct the coding style, however, for -net it 
should be user visible bugs.

I'll go ahead and apply this to iwl-next without a re-send, but please 
keep Przemek's comments in mind for future submissions.

Thanks,
