Subject: [PATCH v3 2/3] mmc: core: Drop check for mmc_card_is_removable() in mmc_rescan()
Date: Tue, 12 Nov 2019 13:40:20 +0100 [thread overview]
Message-ID: <20191112124021.8718-3-ulf.hansson@linaro.org> (raw)
In-Reply-To: <20191112124021.8718-1-ulf.hansson-QSEj5FYQhm4dnm+yROfE0A@public.gmane.org>
Upfront in mmc_rescan() we use the host->rescan_entered flag, to allow
scanning only once for non-removable cards. Therefore, it's also not
possible that we can have a corresponding card bus attached (host->bus_ops
is NULL), when we are scanning non-removable cards.
For this reason, let' drop the check for mmc_card_is_removable() as it's
redundant.
