USB: storage: Remove redundant license text

2017-11-04T10:55:38+00:00

Now that the SPDX tag is in all USB files, that identifies the license in a specific and legally-defined manner. So the extra GPL text wording can be removed as it is no longer needed at all. This is done on a quest to remove the 700+ different ways that files in the kernel describe the GPL license text. And there's unneeded stuff like the address (sometimes incorrect) for the FSF which is never needed. No copyright headers or other non-license-description text was removed.

USB: add SPDX identifiers to all remaining files in drivers/usb/

2017-11-04T10:48:02+00:00

It's good to have SPDX identifiers in all files to make it easier to audit the kernel tree for correct licenses. Update the drivers/usb/ and include/linux/usb* files with the correct SPDX license identifier based on the license text in the file itself. The SPDX identifier is a legally binding shorthand, which can be used instead of the full boiler plate text. This work is based on a script and data from Thomas Gleixner, Philippe Ombredanne, and Kate Stewart.

usb: storage: return on error to avoid a null pointer dereference

2017-07-17T11:11:57+00:00

When us->extra is null the driver is not initialized, however, a later call to osd200_scsi_to_ata is made that dereferences us->extra, causing a null pointer dereference. The code currently detects and reports that the driver is not initialized; add a return to avoid the subsequent dereference issue in this check. Thanks to Alan Stern for pointing out that srb->result needs setting to DID_ERROR << 16 Detected by CoverityScan, CID#100308 ("Dereference after null check") Signed-off-by: Colin Ian King Cc: stable Acked-by: Alan Stern Signed-off-by: Greg Kroah-Hartman

usb: storage: fix multi-line comment style

USB: rewrite isd200_init_info for readability

2015-10-04T09:51:58+00:00

Previously, Coccinelle would issue the following false positive: isd200.c:1478:14-18: ERROR: reference preceded by free on line 1472 This change rewrites the isd200_init_info function to have more explicit execution pathways to make it easier for scripts and humans to parse.

usb: storage: fix module reference for scsi host

2015-05-10T14:03:50+00:00

While accessing a unusual usb storage (ums-alauda, ums-cypress, ...), the module reference count is not incremented. Because these drivers allocate scsi hosts with usb_stor_host_template defined in usb-storage module. So these drivers always can be unloaded. This fixes it by preparing scsi host template which is initialized at module_init() for each ums-* driver. In order to minimize the difference in ums-* drivers, introduce module_usb_stor_driver() helper macro which is same as module_usb_driver() except that it also initializes scsi host template.

usb: storage: Convert US_DEBUGP to usb_stor_dbg

2013-04-19T18:46:50+00:00

Use a more current logging style with dev_printk where possible. o Convert uses of US_DEBUGP to usb_stor_dbg o Add "struct us_data *" to usb_stor_dbg uses o usb_stor_dbg now uses struct device */dev_vprint_emit o Removed embedded function names o Coalesce formats o Remove trailing whitespace o Remove useless OOM messages o Remove useless function entry/exit logging o Convert some US_DEBUGP uses to dev_info and dev_dbg Object size is slightly reduced when debugging is enabled, slightly increased with no debugging because some initialization and removal messages are now always emitted.

usb: storage: Add usb_stor_dbg, reduce object size

2013-04-17T17:01:22+00:00

Reduce the size of the objects by consolidating the duplicated USB_STORAGE into a single function. Add function usb_stor_dbg to emit debugging messages. Always validate the format and arguments. Reduce the number of uses of CONFIG_USB_STORAGE_DEBUG. Reduces size of objects ~7KB when CONFIG_USB_STORAGE_DEBUG is set. $ size drivers/usb/storage/built-in.o* text data bss dec hex filename 140133 55296 70312 265741 40e0d drivers/usb/storage/built-in.o.new 147494 55248 70296 273038 42a8e drivers/usb/storage/built-in.o.old Signed-off-by: Joe Perches Signed-off-by: Greg Kroah-Hartman
