usb: Correct return value in usb_stor_info()

2016-03-22T16:16:28+00:00

This should return 0 on success, not 1. Fix it.

Fix spelling of "transferred".

dm: usb: Convert USB storage to use driver-model for block devs

2016-03-14T21:34:50+00:00

Update this code to support CONFIG_BLK. Each USB storage device can have
one or more block devices as children, each one representing a LUN
(logical unit) of the USB device.

dm: usb: Tidy up storage code ready for driver model conversion

2016-03-14T21:34:50+00:00

Adjust a few things so that the addition of driver-models support involved
adding code rather than also changing it. This makes the patches easier to
review.

dm: usb: Avoid exceeding available array size for storage devices

2016-03-14T21:34:50+00:00

The limit on storage devices is USB_MAX_STOR_DEV but we use one extra
element while probing to see if a device is a storage device. Avoid this,
since it causes memory corruption.

dm: block: Rename device number member dev to devnum

2016-03-14T21:34:50+00:00

This is a device number, and we want to use 'dev' to mean a driver model
device. Rename the member.

dm: part: Rename some partition functions

2016-03-14T21:34:50+00:00

Rename three partition functions so that they start with part_. This makes
it clear what they relate to.

dm: Drop the block_dev_desc_t typedef

2016-03-14T21:34:50+00:00

Use 'struct' instead of a typdef. Also since 'struct block_dev_desc' is long
and causes 80-column violations, rename it to struct blk_desc.

usb: Define USB_MAX_STOR_DEV in only one place

2016-01-21T02:06:23+00:00

We can define this in the header file and use it in usb_storage.c. There is
no need to define it twice. Remove the #define from usb_storage.c.

block: pass block dev not num to read/write/erase()

2016-01-14T02:05:18+00:00

This will allow the implementation to make use of data in the block_dev
structure beyond the base device number. This will be useful so that eMMC
block devices can encompass the HW partition ID rather than treating this
out-of-band. Equally, the existence of the priv field is crying out for
this patch to exist.
