cpufreq: scmi: Avoid overflow of target_freq in fast switch

Browse source

[ Upstream commit 074cffb502 ]

Conversion of target_freq to HZ in scmi_cpufreq_fast_switch()
can lead to overflow if the multiplied result is greater than
UINT_MAX, since type of target_freq is unsigned int. Avoid this
overflow by assigning target_freq to unsigned long variable for
converting it to HZ.
