Subject: [PATCH net-next v3] net: sfp: Unique GPIO interrupt names

From: Chris Healy <[email protected]>

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.

Signed-off-by: Chris Healy <[email protected]>

v3:
- reverse Christmas tree new variable
- fix spaces vs tabs
v2:
- added net-next to PATCH part of subject line
- switched to devm_kasprintf()

Good point. I will add this. I see this patch was just applied so
I'll submit a follow on patch to add the appropriate error check.
