X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=99dc9d95ec5a20dddb9f4462d576c63bfc06d8ad;p=openwrt%2Fstaging%2Fblogic.git

mtd: rawnand: fsl_elbc: return meaningful values

Return -ENOTSUPP instead of -1 from ->chip_init_tail() before migrating
this driver to use nand_scan() and transform this function to be a
callback run by the core.
