Subject[PATCH] aic7xxx_old: silence GCC warnings
From
Date
Building the aic7xxx_old driver triggers these GCC warnings:
drivers/scsi/aic7xxx_old.c:7901:5: warning: case value '257' not in enumerated type 'ahc_chip' [-Wswitch]
drivers/scsi/aic7xxx_old.c:7898:5: warning: case value '513' not in enumerated type 'ahc_chip' [-Wswitch]
drivers/scsi/aic7xxx_old.c:8517:5: warning: case value '257' not in enumerated type 'ahc_chip' [-Wswitch]
drivers/scsi/aic7xxx_old.c:8510:5: warning: case value '513' not in enumerated type 'ahc_chip' [-Wswitch]

Fix these warnings by adopting the idiom used elsewhere in this driver.
Since AHC_EISA and AHC_VL are only ever set for AHC_AIC7770 this fix
should not lead to any functional change.

0) I noticed these warnings while building v3.6-rc6 on current Fedora
17, using Fedora's default config.

1) Compile tested only.

2) This patch is not checkpatch clean. But this file actually triggers
thousands of checkpatch errors and warnings:
total: 4779 errors, 7528 warnings, 11149 lines checked

So I didn't bother to fix the few errors and warnings this patch
triggers by sticking to this file (lack of) coding style.
