Subject: [PATCH net-next 6/6] net: ipa: move IPA flags field
Date: Wed, 4 Aug 2021 10:36:26 -0500 [thread overview]
Message-ID: <20210804153626.1549001-7-elder@linaro.org> (raw)
In-Reply-To: <20210804153626.1549001-1-elder@linaro.org>
The ipa->flags field is only ever used in "ipa_clock.c", related to
suspend/resume activity.
Move the definition of the ipa_flag enumerated type to "ipa_clock.c".
And move the flags field from the ipa structure and to the ipa_clock
structure. Rename the type and its values to include "power" or
"POWER" in the name.
