Subject: [PATCH 12/17] media: camss: vfe-170: clean up some dead code
Date: Tue, 11 May 2021 14:07:19 -0400 [thread overview]
Message-ID: <20210511180728.23781-13-jonathan@marek.ca> (raw)
In-Reply-To: <20210511180728.23781-1-jonathan@marek.ca>
vfe_isr_read()/vfe_isr_halt_ack()/vfe_reg_clr() are never called.
vfe_isr_sof() does nothing, remove it.
The only vfe_reg_set() usage can be easily replaced with a writel.
Fixes: 7319cdf189bb ("media: camss: Add support for VFE hardware version Titan 170")
Signed-off-by: Jonathan Marek <jonathan@marek.ca>
