[v1] accel/amdxdna: Add missing include linux/slab.h

[PATCH] accel/amdxdna: Add missing include linux/slab.h

Posted by Su Hui 12 months ago

When compiling without CONFIG_IA32_EMULATION, there are some errors:

drivers/accel/amdxdna/amdxdna_mailbox.c: In function ‘mailbox_release_msg’:
drivers/accel/amdxdna/amdxdna_mailbox.c:197:2: error: implicit declaration
of function ‘kfree’.
  197 |  kfree(mb_msg);
      |  ^~~~~
drivers/accel/amdxdna/amdxdna_mailbox.c: In function ‘xdna_mailbox_send_msg’:
drivers/accel/amdxdna/amdxdna_mailbox.c:418:11: error:implicit declaration
of function ‘kzalloc’.
  418 |  mb_msg = kzalloc(sizeof(*mb_msg) + pkg_size, GFP_KERNEL);
      |           ^~~~~~~

Add the missing include.

Hi,

please move the header to the include block above an keep it sorted:
#include <linux/iopoll.h>
-->#include <linux/slab.h><--
#include <linux/xarray.h>
