[ Upstream commit 2dc2ca9000eea2eb749f658196204cb84d4306f7 ]
./drivers/clk/tegra/clk-periph.c:59:5-9: WARNING: Unsigned expression compared with zero: rate < 0
The unsigned long 'rate' variable caused: - Incorrect handling of negative errors - Compile warning: "Unsigned expression compared with zero"
Fix by changing to long type and adding req->rate cast.
