Subject: [RFT PATCH v2 04/10] drivers: qcom: rpmh-rsc: Remove get_tcs_of_type() abstraction
Date: Wed, 11 Mar 2020 16:13:42 -0700	[thread overview]
Message-ID: <20200311161104.RFT.v2.4.Ia348ade7c6ed1d0d952ff2245bc854e5834c8d9a@changeid> (raw)
In-Reply-To: <20200311231348.129254-1-dianders@chromium.org>

The get_tcs_of_type() function doesn't provide any value.  It's not
conceptually difficult to access a value in an array, even if that
value is in a structure and we want a pointer to the value.  Having
the function in there makes me feel like it's doing something fancier
like looping or searching.  Remove it.
