Subject: clk: scpi: fix return type of __scpi_dvfs_round_rate
From: Sudeep Holla <sudeep.holla@arm.com>
[ Upstream commit 7374aec95636ca39409545eba4ef5ff3125c2346 ]
The frequencies above the maximum value of signed integer(i.e. 2^31 -1)
will overflow with the current code.
This patch fixes the return type of __scpi_dvfs_round_rate from 'int'
to 'unsigned long'.
Fixes: cd52c2a4b5c4 ("clk: add support for clocks provided by SCP(System Control Processor)")
