[PATCH net-next v2] net: sfp: Unique GPIO interrupt names

[PATCH net-next v2] net: sfp: Unique GPIO interrupt names

[Chris Healy]

Dynamically generate a unique GPIO interrupt name, based on the
device name and the GPIO name.  For example:

103:          0   sx1503q  12 Edge      sff2-los
104:          0   sx1503q  13 Edge      sff2-tx-fault

The sffX indicates the SFP the los and tx-fault are associated with.

v2:
- added net-next to PATCH part of subject line
- switched to devm_kasprintf()

Hi Chris

Reverse Christmas tree.

Did you run ./scripts/checkpatch.pl on this patch? I suspect it will
complain about spaces, not tabs.

Humm, actually, all tabs seem to of been converted to spaces.

Something David often recommends. email the patch to yourself, and
then apply it using git am. If it does not apply cleanly, something
has mangled it.
