[media] saa7115: Don't use a dynamic array

    drivers/media/i2c/saa7115.c: In function 'saa711x_detect_chip.constprop.2':

While for me the above report seems utterly bogus, as the
compiler should be optimizing saa711x_detect_chip, merging
it with saa711x_detect_chip and changing:
char chip_ver[size - 1];
to
char chip_ver[16];

because this function is only called on this code snippet:
char name[17];
...
ident = saa711x_detect_chip(client, id, name, sizeof(name));

It seems that gcc is not optimizing it, at least on s390.

As getting rid of it is easy, let's do it.

[media] saa7115: Add register setup and config for gm7113c

The gm7113c chip is similar to the original saa7113 chip, so I try to
re-use most of the saa7113 specific setup-/configuration registers.
According to the datasheet, the gm7113c chip has not implemented
any register-addresses after 0x1f, so I add a new entry to for the chip
to the saa711x_has_reg function.
The devices I've seen using this chip will fail to get stable video-sync
if these registers are not zeroed:
R_14_ANAL_ADC_COMPAT_CNTL
R_15_VGATE_START_FID_CHG
R_16_VGATE_STOP
R_17_MISC_VGATE_CONF_AND_MSB
The saa711x_set_v4lstd is updated to send a simpler configuration-table
to avoid setting these registers.

 - Improved platform support, in particular the Netlogic XLR and

 - Complete support for the microMIPS ASE which basically reencodes the
   existing MIPS32/MIPS64 ISA to use non-constant size instructions.

 - Some fallout from LTO work which remove old cruft and will generally
   make the MIPS kernel easier to maintain and resistant to compiler
   optimization, even in absence of LTO.

 - KVM support.  While MIPS has announced hardware virtualization
   extensions this KVM extension uses trap and emulate mode for
   virtualization of MIPS32.  More KVM work to add support for VZ

[SCSI] sas: unify the pointlessly separated enums sas_dev_type and sas_device_type

These enums have been separate since the dawn of SAS, mainly because the
latter is a procotol only enum and the former includes additional state
for libsas.  The dichotomy causes endless confusion about which one you
should use where and leads to pointless warnings like this:

one, but call it sas_device_type and make sure the enums are all
properly namespaced with the SAS_ prefix.
