It may endup with divide by zero scenario resulting in kernel panic. Let's set the multiplication factor to one if either one or both of them (sustained_perf_level and sustained_freq) are set to zero.

They generally just improve code readability, fix kernel-docs, remove unused/unnecessary code, follow standard function naming and simplifies certain exit paths. * tag 'scmi-updates-4.18' of git://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux: firmware: arm_scmi: simplify exit path by returning on error firmware: arm_scmi: improve exit paths and code readability firmware: arm_scmi: remove unnecessary bitmap_zero firmware: arm_scmi: drop unused `con_priv` structure member firmware: arm_scmi: rename scmi_xfer_{init,get,put} firmware: arm_scmi: rename get_transition_latency and add_opps_to_device firmware: arm_scmi: fix kernel-docs documentation firmware: arm_scmi: improve code readability using bitfield accessor macros Signed-off-by: Olof Johansson <olof@lixom.net> 2018-05-14T08:05:00Z Olof Johansson 2018-05-14T08:05:00Z urn:sha1:16145fff375011ac7e82930aeb4dfa3b23a52ebe SCMI fix for v4.17 A single patch to ensure that the scmi device is not used for setting up scmi handle after it's freed(fixes use after free). * tag 'scmi-fixes-4.17' of git://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux: firmware: arm_scmi: Use after free in scmi_create_protocol_device() Signed-off-by: Olof Johansson <olof@lixom.net> 2018-05-10T09:52:00Z Sudeep Holla 2018-05-09T16:52:06Z urn:sha1:632de8f542bcd44c756637da0e7d824e7129e496 Yet another nasty indentation left out during code restructuring.

It's obvious to have more readable code with a goto used for the error path. This patch adds more appropriate error paths and makes code more readable. It also moves a error logging outside the scope of locking.

But after some discussions, the idea was dropped but this variable slipped through the cracks. This patch gets rid of this unused variable.

While I agree to some extent, the reason not to have alloc/free as these are preallocated buffers and these functions just returns a reference to free slot in that preallocated array. However it was agreed to drop "_one" as it's implicit that we are always dealing with one slot anyways. This patch updates the name accordingly dropping "_one" in both {get,put} functions. Also scmi_one_xfer_init is renamed as scmi_xfer_get_init to reflect the fact that it gets the free slots and then initialise it.

This patch fixes them so that all the functions names are aligned to that practice. [0] https://www.spinics.net/lists/arm-kernel/msg583673.html Acked-by: Rafael J.
