dmaengine: mmp-pdma: add number of requestors

2016-05-04T21:49:16+00:00

commit c283e41ef32442f41e7180f9bb1c5aedf9255bfe upstream. The DMA chip has a fixed number of requestor lines used for flow control. This number is platform dependent. The pxa_dma dma driver will use this value to activate or not the flow control. There won't be any impact on mmp_pdma driver. Signed-off-by: Robert Jarzmik Signed-off-by: Greg Kroah-Hartman

extcon: max77843: Use correct size for reading the interrupt register

2016-05-04T21:49:16+00:00

commit c4924e92442d7218bd725e47fa3988c73aae84c9 upstream. The info->status[] array has 3 elements. We are using size MAX77843_MUIC_IRQ_NUM (16) instead of MAX77843_MUIC_STATUS_NUM (3) as intended.

stm class: Select CONFIG_SRCU

2016-05-04T21:49:16+00:00

commit 042d4460b5b4379a12f375045ff9065cf6758735 upstream. The newly added STM code uses SRCU, but does not ensure that this code is part of the kernel: drivers/built-in.o: In function `stm_source_link_show': include/linux/srcu.h:221: undefined reference to `__srcu_read_lock' include/linux/srcu.h:238: undefined reference to `__srcu_read_unlock' drivers/built-in.o: In function `stm_source_link_drop': include/linux/srcu.h:221: undefined reference to `__srcu_read_lock' include/linux/srcu.h:238: undefined reference to `__srcu_read_unlock' This adds a Kconfig 'select' statement like all the other SRCU using drivers have.

tpm: fix: set continueSession attribute for the unseal operation

2016-05-04T21:49:15+00:00

commit c0b5eed110dcf520aadafefbcc40658cbdd18b95 upstream. It's better to set the continueSession attribute for the unseal operation so that the session object is not removed as a side-effect when the operation is successful. Since a user process created the session, it should be also decide when the session is destroyed.

tpm: fix checks for policy digest existence in tpm2_seal_trusted()

commit f3c82ade7c59303167d56b0be3e0707751fc45e2 upstream. In my original patch sealing with policy was done with dynamically allocated buffer that I changed later into an array so the checks in tpm2-cmd.c became invalid. This patch fixes the issue.

megaraid_sas: add missing curly braces in ioctl handler

commit 3deb9438d34a09f6796639b652a01d110aca9f75 upstream. gcc-6 found a dubious indentation in the megasas_mgmt_fw_ioctl function: drivers/scsi/megaraid/megaraid_sas_base.c: In function 'megasas_mgmt_fw_ioctl': drivers/scsi/megaraid/megaraid_sas_base.c:6658:4: warning: statement is indented as if it were guarded by...

sunrpc/cache: drop reference when sunrpc_cache_pipe_upcall() detects a race

2016-05-04T21:49:15+00:00

commit a6ab1e8126d205238defbb55d23661a3a5c6a0d8 upstream. sunrpc_cache_pipe_upcall() can detect a race if CACHE_PENDING is no longer set. In this case it aborts the queuing of the upcall. However it has already taken a new counted reference on "h" and doesn't "put" it, even though it frees the data structure holding the reference. So let's delay the "cache_get" until we know we need it. Fixes: f9e1aedc6c79 ("sunrpc/cache: remove races with queuing an upcall.") Signed-off-by: NeilBrown Signed-off-by: J.

unbreak allmodconfig KCONFIG_ALLCONFIG=...

2016-05-04T21:49:15+00:00

commit 6b87b70c5339f30e3c5b32085e69625906513dc2 upstream. Prior to 3.13 make allmodconfig KCONFIG_ALLCONFIG=/dev/null used to be equivalent to make allmodconfig; these days it hardwires MODULES to n. In fact, any KCONFIG_ALLCONFIG that doesn't set MODULES explicitly is treated as if it set it to n. Regression had been introduced by commit cfa98f ("kconfig: do not override symbols already set"); what happens is that conf_read_simple() does sym_calc_value(modules_sym) on exit, which leaves SYMBOL_VALID set and has conf_set_all_new_symbols() skip modules_sym. It's pretty easy to fix - simply move that call of sym_calc_value() into the callers, except for the ones in KCONFIG_ALLCONFIG handling. Objections?
