2019-03-29staging: comedi: ni_tio: Use data[insn->n-1] in ni_tio_insn_write()Ian Abbott1-6/+8
The `insn_write` handler for the counter subdevices (`ni_tio_insn_write()`) writes a single data value `data[0]` to the channel. Technically, `insn->n` specifies the number of successive values from `data[]` to write to the channel, but when there is little benefit in writing multiple data values, the usual Comedi convention is to just write the last data value `data[insn->n - 1]`. Change the function to follow that convention and use `data[insn->n - 1]` instead of `data[0]`. (In practice, `insn->n` would normally be 1 anyway.) Also follow the usual Comedi convention and return `insn->n` from the handler to indicate success instead of 0 (although any non-negative return value will do).

2019-03-29media: staging: media: imx7-mipi-csis: fix debugfs compilationArnd Bergmann1-14/+2
When CONFIG_DEBUGFS is enabled, we get a warning about an incorrect section annotation that can lead to undefined behavior: WARNING: vmlinux.o(.text+0xd3c7c4): Section mismatch in reference from the function mipi_csis_probe() to the function .init.text:mipi_csis_debugfs_init() The function mipi_csis_probe() references the function __init mipi_csis_debugfs_init(). This is often because mipi_csis_probe lacks a __init annotation or the annotation of mipi_csis_debugfs_init is wrong. The same function for an unknown reason has a different version for !CONFIG_DEBUGFS, which does not have this problem, but behaves the same way otherwise (it does nothing when debugfs is disabled). Consolidate the two versions, using the correct section from one version, and the implementation from the other.

2019-03-27staging: mt7621-mmc: Initialize completions a single time during probeGeorge Hilliard1-4/+14
The module was initializing completions whenever it was going to wait on them, and not when the completion was allocated. This is incorrect according to the completion docs: Calling init_completion() on the same completion object twice is most likely a bug [...] Re-initialization is also unnecessary because the module never uses complete_all(). Fix this by only ever initializing the completion a single time, and log if the completions are not consumed as intended (this is not a fatal problem, but should not go unnoticed).
