Subject: [PATCH] bus: mhi: core: Update comments on mhi_prepare_for_power_up
Date: Thu, 26 Aug 2021 10:32:55 -0600	[thread overview]
Message-ID: <> (raw)

From: Pranjal Ramajor Asha Kanojiya <>

After "bus: mhi: core: Remove pre_init flag used for power purposes"
mhi_prepare_for_power_up() is no longer an optional API. All users
of MHI should call this API before power up sequence to initialize
MHI context. Update the comments on this API to make this clear.

Fixes: eee87072e2fb ("bus: mhi: core: Remove pre_init flag used for power purposes")
