Subject: [PATCH V1 4/4] spmi: pmic-arb: Remove checking opc value not less than 0

From: Fenglin Wu <fenglinw@...eaurora.org>

The opc parameter in pmic_arb_write_cmd() function is defined with type
u8 and it's always greater than or equal to 0. Checking that it's not
less than 0 is redundant and it can cause a forbidden warning during
compilation. Remove the check.
