This new revision contains a few bug fixes, but mostly features small code changes and minor improvements. In terms of bugs there were bugs in the sensor code. There was an overflow issue and EV_MSC/MSC_TIMESTAMP were not set on the device. In addition, the ps_device spinlock was not initialized. The biggest change in the driver was the addition of a new 'ps_get_report' helper function. It handles GET_FEATURE report retrieval and any error handling including CRC checks for PlayStation Bluetooth devices. This greatly simplified all the functions (dualsense_get_mac_address, dualsense_calibration_info, ..) dealing, which used their own report handling and error checking. Aside for these changes, there were mostly little code style changes like defining magic constants, cleaning up comments, cleaning up log messages, static_assert checks etcetera. Thanks to everyone who provided feedback through the mailing list or privately. Changes since v2: - Removed !Expert setting for hid-playstation from Kconfig. - Removed DualSense from hid-quirks table. - Added report size checks to dualsense_parse_report. - Moved mac address endianess comment to struct ps_device. - Added static_asserts for packed structure size checks. - Improved readability of battery capacity calculation using 'min'. - Added spin_lock_init to dualsense_create to initialize ps_device lock. - Fixed sensors timestamp overflow. - Fixed missing MSC_TIMESTAMP and EV_MSC capabilities in ps_sensors_create. - Used DIV_ROUND_CLOSEST for timestamp calculations to minimize rounding errors. - Switched to devm_kmalloc_array for lightbar allocation. - Added CRC32 and NEW_LEDS dependency to Kconfig. - Added defines for crc32 seed constants. - Added crc32 check for dualsense_get_mac_address and increased report size to 20. - Added new ps_get_report call to obtain feature reports. - Switched to ARRAY_SIZE in dualsense_parse_reports for touch points, accel and gyro data. - Changed touch point parse loop to use "struct dualsense_touch_point". - Improved consistency of info and error messages. - Unified comment style.
