Subject: PCI/AER: Clean up error printing code a bit
X-Git-Tag: v3.14-rc1~132^2~26^2~2
X-Git-Url: https://openfabrics.org/gitweb/?a=commitdiff_plain;h=1c38108a086f1cca3700765607059a6d865910c2;p=~emulex%2Finfiniband.git

PCI/AER: Clean up error printing code a bit

Save one indentation level in aer_print_error() for the generic case where
we have info->status of an error, disregard 80 cols rule a bit for the sake
of better readability, fix alignment.

No functionality change.
