Subject: [patch 1/2 v2] qlcnic: clean up qlcnic_init_pci_info()
Date: Tue, 10 Aug 2010 07:47:56 +0000 [thread overview]
Message-ID: <20100810074756.GF18431@bicker> (raw)
In the original code we allocated memory conditionally and freed it in
the error handling unconditionally. It turns out that this function is
only called during initialization and "adapter->npars" and
"adapter->eswitch" are always NULL at the start of the function. I
removed those checks.
Also since I was cleaning things, I changed the error handling for
qlcnic_get_pci_info() and pulled everything in an indent level.

V2: fixed a typo. I set eswitch to NULL twice instead of npars by
mistake.
