This patch annotates pointers as referring to I/O mapped memory where they ought to be, removes now unnecessary ugly casts, eliminates an incorrect deref on I/O mapped memory by using iowrite16 instead, and updates the pointer arithmetic accordingly to take into account that the pointers are now byte-sized. This fixes the following sparse warnings:- drivers/staging/sm750fb/sm750_cursor.c:113:19: warning: cast removes address space of expression drivers/staging/sm750fb/sm750_cursor.c:204:19: warning: cast removes address space of expression Signed-off-by: Lorenzo Stoakes <lstoakes@gmail.com> --- v2: Whitespace fixups drivers/staging/sm750fb/sm750_cursor.c | 24 ++++++++++++------------ 1 file changed, 12 insertions(+), 12 deletions(-) -- 2.3.2 -- To unsubscribe from this list: send the line "unsubscribe linux-fbdev" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
