intel_th: msu: Fix vmalloced buffers

2022-07-08T13:42:56Z

After commit f5ff79fddf0e ("dma-mapping: remove CONFIG_DMA_REMAP") there's a chance of DMA buffer getting allocated via vmalloc(), which messes up the mmapping code: > RIP: msc_mmap_fault [intel_th_msu] > Call Trace: > > __do_fault > do_fault ... Fix this by accounting for vmalloc possibility.

intel_th: msu: Use memset_startat() for clearing hw header

2022-02-14T00:48:04Z

In preparation for FORTIFY_SOURCE performing compile-time and run-time field bounds checking for memset(), avoid intentionally writing across neighboring fields. Use memset_startat() so memset() doesn't get confused about writing beyond the destination member that is intended to be the starting point of zeroing through the end of the struct.

bus: Make remove callback return void

2021-07-21T09:53:42Z

The driver core ignores the return value of this callback because there is only little it can do when a device disappears. This is the final bit of a long lasting cleanup quest where several buses were converted to also return void from their remove callback. Additionally some resource leaks were fixed that were caused by drivers returning an error code in the expectation that the driver won't go away. With struct bus_type::remove returning void it's prevented that newly implemented buses return an ignored error code and so don't anticipate wrong expectations for driver authors.

intel_th: Wait until port is in reset before programming it

2021-06-24T13:49:32Z

Some devices don't drain their pipelines if we don't make sure that the corresponding output port is in reset before programming it for a new trace capture, resulting in bits of old trace appearing in the new trace capture. Fix that by explicitly making sure the reset is asserted before programming new trace capture.
