mtd: devices: elm: fix elm_context_save() and elm_context_restore() functions

2014-07-28T15:06:03+00:00

commit 6938ad40cb97a52d88a763008935340729a4acc7 upstream.

These two function's switch case lack the 'break' that make them always
return error.

mtd: m25p80: Set rx_nbits for Quad SPI transfers

2014-01-28T05:19:28+00:00

When using the Quad Read opcode, SPI masters still use Single SPI
transfers, as spi_transfer.rx_nbits defaults to SPI_NBITS_SINGLE.
Use SPI_NBITS_QUAD to fix this.

While an earlier version of commit 3487a63955c34ea508bcf4ca5131ddd953876e2d
("drivers: mtd: m25p80: add quad read support") did this correctly, it was
forgotten in the version that got merged.

mtd: m25p80: Enable Quad SPI read transfers for s25fl512s

2014-01-28T05:19:27+00:00

Spansion s25fl512s supports Quad SPI transfers, hence set the
M25P80_QUAD_READ flag.

mtd: m25p80: assign default read command

2014-01-20T19:49:48+00:00

In the following commit (in -next):

    commit 8552b439aba7f32063755d23f79ca27b4d0a3115
    drivers: mtd: m25p80: convert "bool" read check into an enum

We converted the boolean 'fast_read' property to become an enum
'flash_read', but at the same time, we changed the conditional path so
that it doesn't choose a default value in some cases (technically, we
choose the correct default simply by virtue of devm_kzalloc(), which
zeroes this out to be a NORMAL read operation, but still...).

Fix this by setting a default for the 'else' clause.

mtd: m25p80: Use OPCODE_QUAD_READ_4B for 4-byte addressing

2014-01-16T21:02:49+00:00

commit 3487a63955c34ea508bcf4ca5131ddd953876e2d ("drivers: mtd: m25p80: add
quad read support") in -next added both the 3-byte OPCODE_QUAD_READ and the
4-byte OPCODE_QUAD_READ_4B, but incorrectly uses OPCODE_QUAD_READ for both
3-byte and 4-byte addressing.

Use OPCODE_QUAD_READ_4B in the 4-byte case to fix this.

mtd: dataflash: remove unnecessary spi_set_drvdata()

2014-01-03T19:22:20+00:00

The driver core clears the driver data to NULL after device_release
or on probe failure. Thus, it is not needed to manually clear the
device driver data to NULL.
