ARM: 9331/1: ARM/dma-mapping: replace kzalloc() and vzalloc() with kvzalloc()
using kvzalloc() simplifies the code by avoiding the use of different memory allocation functions for different situations, making the code more uniform and readable. Signed-off-by: Chen Haonan <chen.haonan2@zte.com.cn> Signed-off-by: Russell King (Oracle) <rmk+kernel@armlinux.org.uk>
