Use full 64-bit division when rounding range-based clock rates, avoiding divisor truncation and a possible divide-by-zero on 32-bit systems. Rate-limit notification queue-full warnings emitted from interrupt context to prevent printk floods and prolonged system stalls during notification bursts. Also correct a grammar error in the ARM_SCMI_POWER_CONTROL Kconfig help text. Fix the FF-A driver RX/TX buffer sizing logic to respect the maximum buffer size advertised by firmware, while retaining compatibility with older implementations that may reject PAGE_SIZE-rounded buffers. Also fix a NULL pointer dereference in ffa_partition_info_get() by rejecting NULL UUID strings before passing them to uuid_parse(). * tag 'scmi-ffa-fixes-7.2' of https://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux: firmware: arm_scmi: Rate-limit queue-full warnings in IRQ context firmware: arm_scmi: Use 64-bit division for clock rate rounding firmware: arm_scmi: Grammar s/may needed/may be needed/ firmware: arm_ffa: Fix NULL dereference in ffa_partition_info_get() firmware: arm_ffa: Respect firmware advertised RX/TX buffer size limits Signed-off-by: Arnd Bergmann --- add11ea55f2d26d798c058fe4d67fb2941e77523
