2016-01-07ncr5380: Remove NCR5380_local_declare and NCR5380_setup macrosFinn Thain1-13/+14
The NCR5380_local_declare and NCR5380_setup macros exist to define and initialize a particular local variable, to provide the address of the chip registers needed for the driver's implementation of its NCR5380_read/write register access macros. In cumana_1 and macscsi, these macros generate pointless code like this, struct Scsi_Host *_instance; _instance = instance; In pas16, the use of NCR5380_read/write in pas16_hw_detect() requires that the io_port local variable has been defined and initialized, but the NCR5380_local_declare and NCR5380_setup macros can't be used for that purpose because the Scsi_Host struct has not yet been instantiated. Moreover, these macros were removed from atari_NCR5380.c long ago and now they constitute yet another discrepancy between the two core driver forks. Remove these "optimizations".

Convert Scsi_Cmnd to struct scsi_cmnd and drop the #include "scsi.h". The sun3_NCR5380.c core driver already uses struct scsi_cmnd so converting the other core drivers reduces the diff which makes them easier to unify.

2014-11-20ncr5380: Cleanup host info() methodsFinn Thain1-134/+1
If the host->info() method is not set, then host->name is used by default. For atari_scsi, that is exactly the same text. So remove the redundant info() method. Keep sun3_scsi.c in line with atari_scsi. Some NCR5380 drivers return an empty string from the info() method (arm/cumana_1.c arm/oak.c mac_scsi.c) while other drivers use the default (dmx3191d dtc.c g_NCR5380.c pas16.c t128.c). Implement a common info() method to replace a lot of duplicated code which the various drivers use to announce the same information. This replaces most of the (deprecated) show_info() output and all of the NCR5380_print_info() output. This also eliminates a bunch of code in g_NCR5380 which just duplicates functionality in the core driver.

2014-11-20ncr5380: Remove NCR5380_STATSFinn Thain1-45/+0
The NCR5380_STATS option is only enabled by g_NCR5380 yet it adds clutter to all three core drivers. The atari_NCR5380.c and sun3_NCR5380.c core drivers have a slightly different implementation of the NCR5380_STATS option. Out of all ten NCR5380 drivers, only one of them (g_NCR5380) actually has the code to report on the collected stats. Aside from being unreadable, that code seems to be broken because there's no initialization of timebase. sun3_NCR5380.c and atari_NCR5380.c have the timebase initialization but lack the code to report the stats. Remove all of this code to improve readability and reduce divergence between the three core drivers. This patch and the next one completely eliminate the PRINTP and ANDP pre-processor abuse.

2014-11-20ncr5380: Fix SCSI_IRQ_NONE bugsFinn Thain1-7/+11
Oak scsi doesn't use any IRQ, but it sets irq = IRQ_NONE rather than SCSI_IRQ_NONE. Problem is, the core NCR5380 driver expects SCSI_IRQ_NONE if it is to issue IDENTIFY commands that prevent target disconnection. And, as Geert points out, IRQ_NONE is part of enum irqreturn. Other drivers, when they can't get an IRQ or can't use one, will set host->irq = SCSI_IRQ_NONE (that is, 255). But when they exit they will attempt to free IRQ 255 which was never requested. Fix these bugs by using NO_IRQ in place of SCSI_IRQ_NONE and IRQ_NONE. That means IRQ 0 is no longer probed by ISA drivers but I don't think this matters. Setting IRQ = 255 for these ISA drivers is understood to mean no IRQ. This remains supported so as to avoid breaking existing ISA setups (which can be difficult to get working) and because existing documentation (SANE, TLDP etc) describes this usage for the ISA NCR5380 driver options.

2007-11-25[SCSI] NCR5380: Fix bugs and canonicalize irq handler usageJeff Garzik1-2/+3
* Always pass the same value to free_irq() that we pass to request_irq(). This fixes several bugs. * Always call NCR5380_intr() with 'irq' and 'dev_id' arguments. Note, scsi_falcon_intr() is the only case now where dev_id is not the scsi_host. * Always pass Scsi_Host to request_irq(). For most cases, the drivers already did so, and I merely neated the source code line. In other cases, either NULL or a non-sensical value was passed, verified to be unused, then changed to be Scsi_Host in anticipation of the future. In addition to the bugs fixes, this change makes the interface usage consistent, which in turn enables the possibility of directly referencing Scsi_Host from all NCR5380_intr() invocations.

2007-02-14[PATCH] remove many unneeded #includes of sched.hTim Schmielau1-1/+0
After Al Viro (finally) succeeded in removing the sched.h #include in module.h recently, it makes sense again to remove other superfluous sched.h includes. There are quite a lot of files which include it but don't actually need anything defined in there. Presumably these includes were once needed for macros that used to live in sched.h, but moved to other header files in the course of cleaning it up. To ease the pain, this time I did not fiddle with any header files and only removed #includes from .c-files, which tend to cause less trouble. Compile tested against 2.6.20-rc2 and 2.6.20-rc2-mm2 (with offsets) on alpha, arm, i386, ia64, mips, powerpc, and x86_64 with allnoconfig, defconfig, allmodconfig, and allyesconfig as well as a few randconfigs on x86_64 and all configs in arch/arm/configs on arm. I also checked that no new warnings were introduced by the patch (actually, some warnings are removed that were emitted by unnecessarily included header files).
