Subject: [PATCH v2 15/35] mtd: spi-nor: core: Call spi_nor_post_sfdp_fixups() only when SFDP is defined
Date: Tue, 27 Jul 2021 07:52:02 +0300	[thread overview]
Message-ID: <20210727045222.905056-16-tudor.ambarus@microchip.com> (raw)
In-Reply-To: <20210727045222.905056-1-tudor.ambarus@microchip.com>

spi_nor_post_sfdp_fixups() was called even when there were no SFDP
tables defined and the function name was misleading.

We introduced the late_init() hook which is used to tweak various
parameters that could not be extracted by other means, i.e. when
parameters are not defined in the JESD216 SFDP standard, or when
the flash_info flags are incomplete.

Use spi_nor_post_sfdp_fixups() just to fix SFDP data. post_sfdp()
hook is as of now used just by s28hs512t, mt35xu512aba, and both
support SFDP, there's no functional change with this patch.
