Subject: [PATCH] PCI: shpchp: Remove surplus variable and ineffectual error check
Date: Thu, 21 May 2020 19:04:57 +0000 [thread overview]
Message-ID: <20200521190457.1066600-1-kw@linux.com> (raw)
Function remove_board() calls shpchp_unconfigure_device() and checks its
return code for a possible error which is unnecessary as
shpchp_unconfigure_device() always returns 0.
Also, remove surplus variable that has not been used for anything. This
will also address the following Coccinelle warning:
drivers/pci/hotplug/shpchp_pci.c:66:5-7: Unneeded variable: "rc".
Return "0" on line 86
