soc: bcm: brcmstb: biuctrl: fix of_iomap leak
Smatch reports:
drivers/soc/bcm/brcmstb/biuctrl.c:291 setup_hifcpubiuctrl_regs() warn:
'cpubiuctrl_base' from of_iomap() not released on lines: 291.
This is because in setup_hifcpubiuctrl_regs(),
cpubiuctrl_base is not released when handle error, which may cause a leak.
To fix this, iounmap is added when handle error.
Fixes: 22f7a9116eba ("soc: brcmstb: Correct CPU_CREDIT_REG offset for Brahma-B53 CPUs")
