Subject: net: mana: Fix a memory leak in an error handling path in 'mana_create_txq()'
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=b90788459cd6d140171b046f0b37fad341ade0a3;p=linux.git

net: mana: Fix a memory leak in an error handling path in 'mana_create_txq()'

If this test fails we must free some resources as in all the other error
handling paths of this function.

Fixes: ca9c54d2d6a5 ("net: mana: Add a driver for Microsoft Azure Network Adapter (MANA)")
