-Subject: [PATCH] mtd: spi-nor: remove WARN_ONCE() message in spi_nor_write()
-
-This patch removes the WARN_ONCE() test in spi_nor_write().
-This macro triggers the display of a warning message almost every time we
-use a UBI file-system because a write operation is performed at offset 64,
-which is in the middle of the SPI NOR memory page. This is a valid
-operation for ubifs.
-
-Hence this warning is pretty annoying and useless so we just remove it.
