2020-07-29nvmem: qcom-spmi-sdam: Enable multiple devicesGuru Das Srinagesh
Using pdev->id as the nvmem's config ID (which, by default, is NVMEM_DEVID_NONE) prevents multiple instances of this driver from probing because of the following error: sysfs: cannot create duplicate filename '/bus/nvmem/devices/spmi_sdam' Use NVMEM_DEVID_AUTO as the NVMEM config ID to fix the issue.

2020-07-29nvmem: qfprom: use NVMEM_DEVID_AUTO for multiple instancesSrinivas Kandagatla
There could be multiple qfprom devices on some SoCs. For example, on MSM8939, qfprom@58000 holds efuse bits for Core Power Reduction (CPR), and qfprom@5c000 holds bits for TSENS. Registering multiple nvmem devices with the same id results in the following failure on the second device.

2020-07-29nvmem: core: add support to auto devidSrinivas Kandagatla
For nvmem providers which have multiple instances, it is required to suffix the provider name with proper id, so that they do not confict for the same name. Currently the core does not handle this case properly eventhough core already has logic to generate the id. This patch add new devid type NVMEM_DEVID_AUTO for providers to be able to allow core to assign id and append it to provier name.

2020-07-29nvmem: Enforce nvmem stride in the sysfs interfaceDouglas Anderson
The 'struct nvmem_config' has a stride attribute that specifies the needed alignment for accesses into the nvmem. This is used in nvmem_cell_info_to_nvmem_cell() but not in the sysfs read/write functions. If the alignment is important in one place it's important everywhere, so let's add enforcement. For now we'll consider it totally invalid to access with the wrong alignment. We could relax this in the read case where we could just read some extra bytes and throw them away. Relaxing it in the write case seems harder (and less safe?) since we'd have to read some data first and then write it back. To keep it symmetric we'll just disallow it in both cases.

2020-07-29binder: Prevent context manager from incrementing ref 0Jann Horn
Binder is designed such that a binder_proc never has references to itself. If this rule is violated, memory corruption can occur when a process sends a transaction to itself; see e.g. <https://syzkaller.appspot.com/bug?extid=09e05aba06723a94d43d>. There is a remaining edgecase through which such a transaction-to-self can still occur from the context of a task with BINDER_SET_CONTEXT_MGR access: - task A opens /dev/binder twice, creating binder_proc instances P1 and P2 - P1 becomes context manager - P2 calls ACQUIRE on the magic handle 0, allocating index 0 in its handle table - P1 dies (by closing the /dev/binder fd and waiting a bit) - P2 becomes context manager - P2 calls ACQUIRE on the magic handle 0, allocating index 1 in its handle table [this triggers a warning: "binder: 1974:1974 tried to acquire reference to desc 0, got 1 instead"] - task B opens /dev/binder once, creating binder_proc instance P3 - P3 calls P2 (via magic handle 0) with (void*)1 as argument (two-way transaction) - P2 receives the handle and uses it to call P3 (two-way transaction) - P3 calls P2 (via magic handle 0) (two-way transaction) - P2 calls P2 (via handle 1) (two-way transaction) And then, if P2 does *NOT* accept the incoming transaction work, but instead closes the binder fd, we get a crash. Solve it by preventing the context manager from using ACQUIRE on ref 0. There shouldn't be any legitimate reason for the context manager to do that. Additionally, print a warning if someone manages to find another way to trigger a transaction-to-self bug in the future.

2020-07-29staging: greybus: audio: Enable GB codec, audio module compilation.Vaibhav Agarwal
Currently you can't enable the Gey Bus Audio Codec because there is no entry for it in the Kconfig file. Originally the config name was going to be AUDIO_MSM8994 but that's not correct because other types of hardware are supported now. I have chosen the name AUDIO_APB_CODEC instead. Also I had to update the dependencies for GREYBUS_AUDIO to make the compile work.

2020-07-29staging: greybus: audio: Add helper APIs for dynamic audio modulesVaibhav Agarwal
Greybus Codec driver allows modules to be dynamically added and removed, which further requires updating the DAPM configurations as well. With current snd_soc architecture, dynamic audio modules is not yet supported. This patch provides helper APIs to update DAPM configurations in response to modules which are dynamically added or removed.

2020-07-29staging: greybus: audio: Maintain jack list within GB Audio moduleVaibhav Agarwal
As per the current implementation for GB codec driver, a jack list is maintained for each module. And it expects the list to be populated by the snd_soc_jack structure which would require modifications in mainstream code. However, this is not a necessary requirement and the list can be easily maintained within gbaudio_module_info as well. This patch provides the relevant changes for the same.
