[PATCH] [media] airspy: Better exception handling in two functions

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx>
Date: Mon, 28 Dec 2015 22:10:28 +0100

This issue was detected by using the Coccinelle software.

Move the jump label directly before the desired log statement
so that the variable "ret" will not be checked once more
after a function call.
Use the identifier "report_failure" instead of "err".

The error logging is performed in a separate section at the end now.
