hw/intc: Pass correct hartid while updating mtimecmp

[PATCH] hw/intc: Pass correct hartid while updating mtimecmp

Posted by Atish Patra 1 year, 11 months ago

timecmp update function should be invoked with hartid for which
timecmp is being updated. The following patch passes the incorrect
hartid to the update function.

Fixes: e2f01f3c2e13 ("hw/intc: Make RISC-V ACLINT mtime MMIO register writable")
