[PATCH] mtd: rawnand: ingenic: fix ingenic_ecc dependency

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The ecc code is called from the main ingenic_nand module, but the
Kconfig symbol gets selected by the dependent ones.

If the child drivers are loadable modules, this leads to a link
error:

drivers/mtd/nand/raw/ingenic/ingenic_nand.o: In function `ingenic_nand_remove':
ingenic_nand.c:(.text+0x1a1): undefined reference to `ingenic_ecc_release'
drivers/mtd/nand/raw/ingenic/ingenic_nand.o: In function `ingenic_nand_ecc_correct':
ingenic_nand.c:(.text+0x1fa): undefined reference to `ingenic_ecc_correct'
drivers/mtd/nand/raw/ingenic/ingenic_nand.o: In function `ingenic_nand_ecc_calculate':
ingenic_nand.c:(.text+0x255): undefined reference to `ingenic_ecc_calculate'
drivers/mtd/nand/raw/ingenic/ingenic_nand.o: In function `ingenic_nand_probe':
ingenic_nand.c:(.text+0x3ca): undefined reference to `of_ingenic_ecc_get'
ingenic_nand.c:(.text+0x685): undefined reference to `ingenic_ecc_release'

Rearrange this to have the ecc code linked the same way as the main
driver.
