| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This thing was completely pointless. Just find the OF device in the parent of drivers that want to program this device, and map the DMA regs inside such drivers too. This also moves the dummy claim_dma_lock() and release_dma_lock() implementation to floppy_32.h, which makes it handle this issue just like floppy_64.h does. Signed-off-by: David S.

It is a reimplementation of the patch posted last week by David Somayajulu. http://marc.info/?l=linux-scsi&m=121745486221819&w=2 There are a few things done differently: - Transport support is included - Event delivery is included - The vendor message is now its own unique message type, considered part of the generic "SCSI Transport". - LLDD entry points are now registered rather than included in the scsi_host_template. Background: When I started to implement the event handler via template, I had to either: muck up scsi_add_host and scsi_remove_host; or have the event handler search all possible shosts. Neither was acceptable. Moving to a registration solves this, and also limits the scope of the changes to something that could be backported to a distro without breaking an already-released-distro kabi. However, I admit it isn't as elegant, as the passing of the LLDD host template in the registration and the complexity around dynamic add/remove shows. - The receive path was augmented to require a unique identifier for the LLDD before the message was allowed to be handed off to the driver. Given how quickly very fatal errors occur if there's msg mismatches (which I saw in testing my own tools :), I believe this to be a very good thing. The id plays off the vendor id scheme already introduced for the vendor unique event messages used by FC. Additionally, the id use as the basis of the registration/deregistration. - Send assist functions, for both the transport and LLDDs are included.

| * | | [SCSI] scsi_host_lookup: error returns and NULL pointersJames Smart2008-10-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch cleans up the behavior of scsi_host_lookup(). The original implementation attempted to use the dual role of either returning a pointer value, or a negative error code. User's needed to use IS_ERR() to check the result. Additionally, the IS_ERR() macro never checks for when a NULL pointer was returned, so a NULL pointer actually passes with a success case. Note: scsi_host_get(), used by scsi_host_lookup(), can return a NULL pointer. Talk about a mudhole for the unitiated to step into.... This patch converts scsi_host_lookup() to return either NULL or a valid pointer. The consumers were updated for the change.
