[PATCH] Renaming 'struct flash_platform_data' into 'struct spi_flash_platform_data' in include/linux/spi/flash.h

As I discussed with Russell King on the list
linux-arm-kernel at lists.infradead.org, there is a problem with the double
definition of 'struct flash_platform_data' that are incompatible:

in arch/arm/include/asm/mach/flash.h:
struct flash_platform_data {
    const char    *map_name;
    const char    *name;
    unsigned int    width;
    int        (*init)(void);
    void        (*exit)(void);
    void        (*set_vpp)(int on);
    void        (*mmcontrol)(struct mtd_info *mtd, int sync_read);
    struct mtd_partition *parts;
    unsigned int    nr_parts;

in include/linux/spi/flash.h:
struct flash_platform_data {
    char        *name;
    struct mtd_partition *parts;
    unsigned int    nr_parts;

    char        *type;

    /* we'll likely add more ... use JEDEC IDs, etc */

Both headers are included in a number of machines or driver.
They make conflict when one has both spi flash and an other type of mtd flash on the same machine (my case).

I suppose the ARM version has no reason not to be platform independent, but that is an other problem.

I propose to rename SPI version of the structure as it is the younger and it is included in a less number of files.
The patch (already sent on linux-arm-kernel at lists.infradead.org) is in attachment.

Best regards,
Alexis RODET
