Pull mailbox fixes from Jussi Brar: "Misc fixes: mailbox-test driver: - prevent memory leak and another cosmetic change mailbox: - change the returned error code Xgene driver: - return -ENOMEM instead of PTR_ERR for failed devm_kzalloc" * 'mailbox-devel' of git://git.linaro.org/landing-teams/working/fujitsu/integration: mailbox: Stop using ENOSYS for anything other than unimplemented syscalls mailbox: mailbox-test: Prevent memory leak mailbox: mailbox-test: Use more consistent format for calling copy_from_user() mailbox: xgene-slimpro: Fix wrong test for devm_kzalloc

mailbox: Stop using ENOSYS for anything other than unimplemented syscalls

2016-04-12T07:58:32Z

In accordance with e15f431fe2d5 ("errno.h: Improve ENOSYS's comment") and 91c9afaf97ee ("checkpatch.pl: new instances of ENOSYS are errors") we're converting from the old meaning of: ENOSYS "Function not implemented" to a more standard EINVAL.

mailbox: mailbox-test: Prevent memory leak

2016-04-12T07:58:30Z

If we set the Signal twice or more, without using it as part of a message, memory will be re-allocated and the pointer over-written. Prevent this potential leak by only allocating memory when there isn't any already. Reported-by: Dan Carpenter Signed-off-by: Lee Jones Signed-off-by: Jassi Brar

mailbox: mailbox-test: Use more consistent format for calling copy_from_user()

2016-04-12T07:58:20Z

While we're at it, ensure copy-to location is NULL'ed in the error path. Suggested-by: Dan Carpenter Signed-off-by: Lee Jones Signed-off-by: Jassi Brar

devm_kzalloc() returns NULL on failure. Signed-off-by: Axel Lin Signed-off-by: Jassi Brar

mailbox: pcc: Don't access an unmapped memory address space

2016-04-06T23:25:28Z

The acpi_pcc_probe() may end up accessing memory outside of the PCCT table space causing the kernel panic(). Increment the pcct_entry pointer after parsing 'HW-reduced Communications Subspace' to fix the problem. This change also enables the parsing of subtable at index 0.

Support for TI Message Manager Module. This hardware block manages a bunch of hardware queues meant for communication between processor entities. Clients sitting on top of this would manage the required protocol for communicating with the counterpart entities.
