Subject: [PATCH] clk: socfpga: fix iomem pointer cast on 64-bit
Pointers should be cast to unsigned long instead of integer. This fixes
warning when compile testing on ARM64:
drivers/clk/socfpga/clk-gate.c: In function ‘socfpga_clk_recalc_rate’:
drivers/clk/socfpga/clk-gate.c:102:7: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast]
