Subject: [SCSI] libfc: Fix compilation warnings with allmodconfig
X-Git-Tag: v2.6.30-rc5~53^2~17
X-Git-Url: http://ftp.safe.ca/?p=safe%2Fjmp%2Flinux-2.6;a=commitdiff_plain;h=a29e7646f42a325a7f6cce34adbeb52e8db15566

[SCSI] libfc: Fix compilation warnings with allmodconfig

When building with a .config generated from 'make allmodconfig'
some build warnings are generated. This patch corrects the warnings,
adds a FC_FID_NONE (= 0) enumeration for FC-IDs and cleans up one
variable naming to meet our variable naming conventions. For example,
fc_lport's should be named "lport," not "lp."
