[PATCH] mtd: nand: stm32: fix wrong regmap_bulk_read() usage

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


Compilation of the STM32 NAND driver fails with:

error: call to '__regmap_bulk_api_changed' declared with attribute error: Last argument is now number of registers, not bytes. Fix it and include <linux/regmap.h instead

Do exactly this to make the driver compile again
