Subject: [PATCH 5/5] bnx2x: Remove hw_reset_t function casts
Date: Thu, 14 Nov 2019 21:07:15 -0800 [thread overview]
Message-ID: <20191115050715.6247-6-keescook@chromium.org> (raw)
In-Reply-To: <20191115050715.6247-1-keescook@chromium.org>
All .rw_reset callbacks except bnx2x_84833_hw_reset_phy() use a
void return type. No callers of .hw_reset check a return value and
bnx2x_84833_hw_reset_phy() unconditionally returns 0. Remove all
hw_reset_t casts and fix the return type to void.
