Subject: [PATCH v1 2/8] mtd: spi-nor: don't clear the SNOR_F_4B_OPCODES flag on failure
Date: Fri,  3 Jul 2026 16:29:13 +0200	[thread overview]
Message-ID: <20260703143003.1809579-3-mwalle@kernel.org> (raw)
In-Reply-To: <20260703143003.1809579-1-mwalle@kernel.org>

This was introduced in commit 548ed6847f530 ("mtd: spi-nor: Add the
SNOR_F_4B_OPCODES flag"). It looks like it was the rollback mechanism if
parsing the SFDP failed, but was setting that flag first. Nowadays, that
flag can only be set if spi_nor_parse_4bait() was successful. IOW, the
flags won't be left in an undefined state if parsing SFDP fails.

Remove the unneeded code to be able to rework spi_nor_init_params().
