Subject: [PATCH v2 18/22] mmc: tmio: remove useless TMIO_MASK_CMD handling in tmio_mmc_host_probe()
Date: Sat, 25 Nov 2017 01:24:53 +0900 [thread overview]
Message-ID: <1511540697-27387-19-git-send-email-yamada.masahiro@socionext.com> (raw)
In-Reply-To: <1511540697-27387-1-git-send-email-yamada.masahiro@socionext.com>
TMIO_MASK_CMD is properly enabled in tmio_mmc_start_command().
We have no reason to set it up in tmio_mmc_host_probe(). (If we
really wanted to set it in the probe, we would have to do likewise
when resuming.)
Even worse, the following code is extremely confusing:
_host->sdcard_irq_mask &= ~irq_mask;
The logic is opposite between "->sdcard_irq_mask" and "irq_mask".
The intention is not clear at a glance.
