mfd: lpc_ich: Add PCI ID for Intel Braswell · ff0c9da0

Alan Cox authored Aug 21, 2014

This is the same as used in Baytrail so add the new PCI ID to the driver's
list of supported IDs.

mfd: da9052-i2c: Remove duplicate test for I2C_FUNC_SMBUS_BYTE_DATA functionality · 378515fc

Axel Lin authored Aug 15, 2014

Since commit b4226107 ("regmap: i2c: fallback to SMBus if the adapter
does not support standard I2C"), regmap-i2c will check the
I2C_FUNC_SMBUS_[BYTE|WORD]_DATA functionality based on the regmap_config
setting if the adapter does not support standard I2C.

So remove the I2C_FUNC_SMBUS_BYTE_DATA functionality check in the driver code.

mfd: menelaus: Fix error return code · 42a71ef9

Julia Lawall authored Aug 21, 2014

Convert a zero return value on error to a negative one, as returned
elsewhere in the function.

Additionally, converted 1 << 7 to BIT(7) at the suggestion of Lee Jones.

A simplified version of the semantic match that finds this problem is as
follows: (http://coccinelle.lip6.fr/)

// <smpl>
(
if@p1 (\(ret < 0\|ret != 0\))
 { ... return ret; }
|
ret@p1 = 0
)
... when != ret = e1
    when != &ret
*if(...)
{
  ... when != ret = e2
      when forall
 return ret;
}

mfd: arizona: Avoid use of legacy IRQ mapping · 2a3377ee

Charles Keepax authored Aug 12, 2014

regmap_add_irq_chip is called from arizona_irq_init with the irq_base
specified as -1 and regmap_add_irq_chip uses if (irq_base) to check if
it should use legacy IRQ mapping. As such the irq mappings are currently
added with irq_domain_add_legacy, rather than irq_domain_add_linear.
This is clearly a typo as there is no reason why this driver can't use
irq_domain_add_linear.

This patch corrects this by passing the irq_base as zero to
regmap_add_irq_chip.

mfd: arizona: Mark additional registers as volatile · e569d937

Charles Keepax authored Aug 13, 2014

Mark some additional registers as volatile. The write sequencer control
registers should not be cached, as we don't ever want their value
synchronised as this might cause a write sequence to be accidentally
initiated.

Additionally, the DAC_COMP registers require special preconditions to
write so there values wouldn't be updated accurately during a register
sync.

mfd: wm5102: Mark register write sequencer control 3 readable · 48018943

Mark Brown authored Aug 13, 2014

During init the core checks if the wm5102 has finished starting by reading
register 0x19 and looking at the value. This read always fails since this
is not a readable register, mark it as being one. While we're at it provide
a constant for the register name (as supplied by Charles Keepax).

mfd: rtsx_usb: Fix decimal printf format specifiers prefixed with 0x · 5e9bbf17

Hans Wennborg authored Aug 05, 2014

The prefix suggests the number should be printed in hex, so use
the %x specifier to do that.

Found by using regex suggested by Joe Perches.

mfd: menelaus: Remove null pointer dereference · e0c8a1f5

Himangi Saraogi authored Aug 09, 2014

If vtg is NULL, it is not possible to access its mode_reg field. At all
sites where the static function menelaus_set_voltage is called, the first
argument is the address of a structure defined in the file. So, the null
test is unnecessary and is removed. Also, a label is done away with.

This problem was found using the following Coccinelle semantic match:

// <smpl>
@@
expression E, E1;
identifier f;
statement S1,S2,S3;
@@

* if (E == NULL)
{
  ... when != if (E == NULL) S1 else S2
      when != E = E1
* E->f
  ... when any
  return ...;
