Subject: [SCSI] libfc: rename lport NONE state to DISABLED
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=b1d9fd5574763abe5c763e32e3547a4adee9bd88;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

[SCSI] libfc: rename lport NONE state to DISABLED

The state NONE was meant to be invalid, but has been used as
the initial state.  Rename it to be DISABLED, as more descriptive.
Further patches will make it the like the RESET state, except
it won't transition to FLOGI until fc_lport_fabric_login() is called.
