2021-08-01samples: mei: don't wait on read completion upon write.Alexander Usyskin
The original mei driver communication was strictly write command and receive response flow, the completion of write was determined when response was ready using select(). This paradigm is a long time not true. There can be write without a response and an unsolicited read. The driver is capable of handling those. Adjust also the sample code and remove select() on read() from the write flow. Add select to the read flow to showcase how to do the read with a timeout.

2020-06-15samples: mei: Replace zero-length array with flexible-arrayGustavo A. R. Silva
There is a regular need in the kernel to provide a way to declare having a dynamically sized set of trailing elements in a structure. Kernel code should always use “flexible array members”[1] for these cases. The older style of one-element or zero-length arrays should no longer be used[2].

2016-09-23samples: move misc-devices/mei example code from DocumentationShuah Khan
Move misc-devices/mei examples to samples/mei and remove it from Documentation Makefile. Delete misc-devices/Makefile. Create a new Makefile to build samples/mei. It can be built from top level directory or from mei directory: Run make -C samples/mei or cd samples/mei; make Acked-by: Jonathan Corbet <corbet@lwn.net> Acked-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Acked-by: Tomas Winkler <tomas.winkler@intel.com> Signed-off-by: Shuah Khan <shuahkh@osg.samsung.com>
