misc: pti: Remove driver for deprecated platform

2021-01-27T12:35:01Z

Intel Moorestown and Medfield are quite old Intel Atom based 32-bit platforms, which were in limited use in some Android phones, tablets and consumer electronics more than eight years ago. There are no bugs or problems ever reported outside from Intel for breaking any of that platforms for years. It seems no real users exists who run more or less fresh kernel on it. The commit 05f4434bc130 ("ASoC: Intel: remove mfld_machine") also in align with this theory. Due to above and to reduce a burden of supporting outdated drivers we remove the support of outdated platforms completely.

misc: pti: Remove unparsable empty line in function header

2020-07-01T13:05:36Z

The kerneldoc tooling/parsers/validators get confused if non- standard formatting is used. The first line after the kerneldoc identifier '/**' must not be blank else the following warnings will be issued: drivers/misc/pti.c:902: warning: Cannot understand * on line 902 - I thought it was a doc line Cc: J Freyensee Signed-off-by: Lee Jones Link: https://lore.kernel.org/r/20200701085853.164358-3-lee.jones@linaro.org Signed-off-by: Greg Kroah-Hartman

misc: pti: Repair kerneldoc formatting issues

2020-07-01T13:05:36Z

W=1 kernel builds report a lack of descriptions for various function arguments. In reality they are documented, but the formatting was not as expected '@.*:'. Instead, '-'s were used as separators. This change fixes the following warnings: drivers/misc/pti.c:748: warning: Function parameter or member 'port' not described in 'pti_port_activate' drivers/misc/pti.c:748: warning: Function parameter or member 'tty' not described in 'pti_port_activate' drivers/misc/pti.c:765: warning: Function parameter or member 'port' not described in 'pti_port_shutdown' drivers/misc/pti.c:793: warning: Function parameter or member 'pdev' not described in 'pti_pci_probe' drivers/misc/pti.c:793: warning: Function parameter or member 'ent' not described in 'pti_pci_probe' Cc: J Freyensee Signed-off-by: Lee Jones Link: https://lore.kernel.org/r/20200701085853.164358-2-lee.jones@linaro.org Signed-off-by: Greg Kroah-Hartman

misc: pti: Fix documentation for bit-rotted function pti_tty_driver_write()

The API has moved on since the original function header was authored. This changes brings the function's documentation back into line with reality, complete descriptions of the latest arguments to be used.

misc: pti: remove redundant assignments to retval

2020-01-14T14:16:51Z

The variable retval is assigned with a value that is never read and it is re-assigned a new value later on. The assignment is redundant and can be removed. Clean up multiple occurrances of this pattern.
