saa7134: fix warm Medion 7134 EEPROM read

2017-07-15T09:57:50+00:00

commit 5a91206ff0d0548939f3e85a65fb76b400fb0e89 upstream.

When saa7134 module driving a Medion 7134 card is reloaded reads of this
card EEPROM (required for automatic detection of tuner model) will be
corrupted due to I2C gate in DVB-T demod being left closed.
This sometimes also happens on first saa7134 module load after a warm
reboot.

Fix this by opening this I2C gate before doing EEPROM read during i2c
initialization.

staging: comedi: fix clean-up of comedi_class in comedi_init()

2017-07-15T09:57:50+00:00

commit a9332e9ad09c2644c99058fcf6ae2f355e93ce74 upstream.

There is a clean-up bug in the core comedi module initialization
functions, `comedi_init()`.  If the `comedi_num_legacy_minors` module
parameter is non-zero (and valid), it creates that many "legacy" devices
and registers them in SysFS.  A failure causes the function to clean up
and return an error.  Unfortunately, it fails to destroy the "comedi"
class that was created earlier.  Fix it by adding a call to
`class_destroy(comedi_class)` at the appropriate place in the clean-up
sequence.

md: fix super_offset endianness in super_1_rdev_size_change

2017-07-15T09:57:49+00:00

commit 3fb632e40d7667d8bedfabc28850ac06d5493f54 upstream.

The sb->super_offset should be big-endian, but the rdev->sb_start is in
host byte order, so fix this by adding cpu_to_le64.

commit 1345921393ba23b60d3fcf15933e699232ad25ae upstream.

The sb->layout is of type __le32, so we shoud use le32_to_cpu.

RDMA/uverbs: Check port number supplied by user verbs cmds

2017-07-15T09:57:47+00:00

commit 5ecce4c9b17bed4dc9cb58bfb10447307569b77b upstream.

The ib_uverbs_create_ah() ind ib_uverbs_modify_qp() calls receive
the port number from user input as part of its attributes and assumes
it is valid. Down on the stack, that parameter is used to access kernel
data structures.  If the value is invalid, the kernel accesses memory
it should not.  To prevent this, verify the port number before using it.

ath10k: override CE5 config for QCA9377

2017-07-15T09:57:47+00:00

commit b08b5b53a1ed2bd7a883f8fd29232c8f03604671 upstream.

Similarly to QCA6174, QCA9377 requires the CE5 configuration to be
available for other feature. Use the ath10k_pci_override_ce_config()
for it as well.

This is required for TF2.0 firmware. Previous FW revisions were
working fine without this patch.

commit 3091ae775fae17084013021d01513bc1ad274e6a upstream.

Update the sh_pfc_soc_info pointer after calling the SoC-specific
initialization function, as it may have been updated to e.g. handle
different SoC revisions.  This makes sure the correct subdriver name is
printed later.
