45e1dccc0653c50e377dae57ef086a8d0f71061d | Analyze and fix the following issue in the Linux kernel code: x86/insn: Simplify for_each_insn_prefix() | Problem Details:
Use the new-found freedom of allowing variable declarions inside
for() to simplify the for_each_insn_prefix() iterator to no longer
need an external temporary.

The PHY_C20_VDR_HDMI_RATE registers 7:2 bits are reserved and they are
not specified as a must-be-zero field. Accordingly this reserved field
shouldn't be zeroed; to ensure that use an RMW to update the
PHY_C20_HDMI_RATE field (which is bits 1:0 of the register).
