soundwire: stream: fix bad unlock balance

2019-07-14T06:09:38Z

[ Upstream commit 9315d904c7e8f38886e2820fa6cb8d0fa723ea21 ] the msg lock is taken for multi-link cases only but released unconditionally, leading to an unlock balance warning for single-link usages This patch fixes this. ===================================== WARNING: bad unlock balance detected! 5.1.0-16506-gc1c383a6f0a2-dirty #1523 Tainted: G W ------------------------------------- aplay/2954 is trying to release lock (&bus->msg_lock) at: do_bank_switch+0x21c/0x480 but there are no more locks to release!

soundwire: stream: fix out of boundary access on port properties

2019-07-14T06:09:36Z

[ Upstream commit 03ecad90d3798be11b033248bbd4bbff4425a1c7 ] Assigning local iterator to array element and using it again for indexing would cross the array boundary. Fix this by directly referring array element without using the local variable. Signed-off-by: Srinivas Kandagatla Acked-by: Pierre-Louis Bossart Signed-off-by: Vinod Koul Signed-off-by: Sasha Levin

soundwire: intel: constify snd_soc_dai_ops structures

2018-11-12T10:06:06Z

The snd_soc_dai_ops structures are only stored in the ops field of a snd_soc_dai_driver structure, so make the snd_soc_dai_ops structures const as well. Done with the help of Coccinelle. Signed-off-by: Julia Lawall Signed-off-by: Vinod Koul

soundwire: intel: Fix uninitialized adev deref

2018-08-27T04:19:48Z

In case of error, we can dereference uninitialized 'adev' drivers/soundwire/intel_init.c:154 sdw_intel_acpi_cb() error: uninitialized symbol 'adev'. Fix that by not using adev for warn print and make it pr_err. Reported-by: Dan Carpenter Acked-by: Pierre-Louis Bossart Signed-off-by: Vinod Koul

soundwire: intel: Add pre/post bank switch ops

2018-08-27T04:19:48Z

To support multi link on Intel platforms, we need to update SDW SHIM registers. So, add pre/post bank switch ops for the same in Intel driver. Signed-off-by: Sanyog Kale Signed-off-by: Shreyas NC Acked-by: Pierre-Louis Bossart Signed-off-by: Vinod Koul

soundwire: keep track of Masters in a stream

2018-08-27T04:19:48Z

A multi link bankswitch can be done if the hardware supports and the stream is handled by multiple Master(s). This preparatory patch adds support to track m_rt in a stream. Modifying m_rt_count and usage is added as part of the next patch. Signed-off-by: Shreyas NC Acked-by: Pierre-Louis Bossart Signed-off-by: Vinod Koul

soundwire: Add support for multi link bank switch

2018-08-27T04:19:48Z

In cases of multiple Masters in a stream, synchronization between multiple Master(s) is achieved by performing bank switch together and using Master methods. Add sdw_ml_bank_switch() to wait for completion of bank switch. Signed-off-by: Sanyog Kale Signed-off-by: Shreyas NC Acked-by: Pierre-Louis Bossart Signed-off-by: Vinod Koul

soundwire: Handle multiple master instances in a stream

2018-08-27T04:19:48Z

For each SoundWire stream operation, we need to parse master list and operate upon all master runtime. This is a preparatory patch to do the boilerplate conversion of stream handling from single master runtime to handle a list of master runtime. The code to support bank switch for multiple master instances is added in the next patch. Signed-off-by: Sanyog Kale Signed-off-by: Shreyas NC Acked-by: Pierre-Louis Bossart Signed-off-by: Vinod Koul
