From d8b57c0a83f9cabc476ca0045c0089195c894b81 Mon Sep 17 00:00:00 2001 From: Kuo-Jung Su Date: Thu, 4 Jul 2013 11:40:36 +0800 Subject: [PATCH] cfi_flash: use buffer length in unmap_physmem() While the flash_detect_legacy() of drivers/mtd/cfi_flash.c feed unmap_physmem() with MAP_NOCACHE as 2nd parameter, the do_spi_flash_read_write() of common/cmd_sf.c feed unmap_physmem() with the length of the mapped buffer as 2nd parameter. It's apparently a bug, and I personally think the 2nd parameter should be the length of the mapped buffer.
