staging: greybus: Fix uninitialized scalar variable

2020-05-13T12:00:21Z

In the "gb_tty_set_termios" function the "newline" variable is declared but not initialized. So the "flow_control" member is not initialized and the OR / AND operations with itself results in an undefined value in this member. The purpose of the code is to set the flow control type, so remove the OR / AND self operator and set the value directly.

staging: kpc2000: fix error return code in kp2000_pcie_probe()

2020-05-13T12:00:20Z

Fix to return a negative error code from the error handling case instead of 0, as done elsewhere in this function. Also removed var 'rv' since we can use 'err' instead.

Check the return value of gasket_get_bar_index function as it can return a negative one (-EINVAL). If this happens, a negative index is used in the "gasket_dev->bar_data" array.

staging: iio: ad2s1210: Fix SPI reading

2020-05-03T11:35:03Z

If the serial interface is used, the 8-bit address should be latched using the rising edge of the WR/FSYNC signal. This basically means that a CS change is required between the first byte sent, and the second one. This change splits the single-transfer transfer of 2 bytes into 2 transfers with a single byte, and CS change in-between. Note fixes tag is not accurate, but reflects a point beyond which there are too many refactors to make backporting straight forward.

staging: comedi: Fix comedi_device refcnt leak in comedi_open

2020-04-23T11:45:24Z

comedi_open() invokes comedi_dev_get_from_minor(), which returns a reference of the COMEDI device to "dev" with increased refcount. When comedi_open() returns, "dev" becomes invalid, so the refcount should be decreased to keep refcount balanced. The reference counting issue happens in one exception handling path of comedi_open(). When "cfp" allocation is failed, the refcnt increased by comedi_dev_get_from_minor() is not decreased, causing a refcnt leak. Fix this issue by calling comedi_dev_put() on this error path when "cfp" allocation is failed.
