mspro_block: remove pointless prep_fn

2017-01-31T21:00:20+00:00

This driver will never see non-fs requests, and doesn't do anything
else in the prep_fn.

drivers/memstick/core/memstick.c: avoid -Wnonnull warning

2017-01-25T00:26:14+00:00

gcc-7 produces a harmless false-postive warning about a possible NULL
pointer access:

  drivers/memstick/core/memstick.c: In function 'h_memstick_read_dev_id':
  drivers/memstick/core/memstick.c:309:3: error: argument 2 null where non-null expected [-Werror=nonnull]
     memcpy(mrq->data, buf, mrq->data_len);

This can't happen because the caller sets the command to 'MS_TPC_READ_REG',
which causes the data direction to be 'READ' and the NULL pointer not
accessed.

As a simple workaround for the warning, we can pass a pointer to the
data that we actually want to read into.  This is not needed here, but
also harmless, and lets the compiler know that the access is ok.

block: split out request-only flags into a new namespace

2016-10-28T14:45:17+00:00

A lot of the REQ_* flags are only used on struct requests, and only of
use to the block layer and a few drivers that dig into struct request
internals.

This patch adds a new req_flags_t rq_flags field to struct request for
them, and thus dramatically shrinks the number of common requests.  It
also removes the unfortunate situation where we have to fit the fields
from the same enum into 32 bits for struct bio and 64 bits for
struct request.

memstick: don't allocate unused major for ms_block

2016-08-02T21:31:41+00:00

When alloc_disk(0) is used the ->major number is completely ignored.
All devices are allocated with a major of BLOCK_EXT_MAJOR.

So remove registration and deregistration of 'major'.

memstick: don't allow REQ_TYPE_BLOCK_PC requests

2016-07-20T23:38:27+00:00

There is no code to issue or handle REQ_TYPE_BLOCK_PC request in the
memstick drivers, so remove the bogus conditional.

block: convert to device_add_disk()

2016-06-27T19:26:08+00:00

For block drivers that specify a parent device, convert them to use
device_add_disk().

This conversion was done with the following semantic patch:

    @@
    struct gendisk *disk;
    expression E;
    @@

    - disk->driverfs_dev = E;
    ...
    - add_disk(disk);
    + device_add_disk(E, disk);

    @@
    struct gendisk *disk;
    expression E1, E2;
    @@

    - disk->driverfs_dev = E1;
    ...
    E2 = disk;
    ...
    - add_disk(E2);
    + device_add_disk(E1, E2);

...plus some manual fixups for a few missed conversions.

drivers/memstick/core/mspro_block: use kmemdup

2016-05-24T00:04:14+00:00

Use kmemdup when some other buffer is immediately copied into allocated
region.  It replaces call to allocation followed by memcpy, by a single
call to kmemdup.
