[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: John Paul Adrian Glaubitz <glaubitz@xxxxxxxxxxxxxxxxxxx>

[ Upstream commit bc9d1f0cecd2407cfb2364a7d4be2f52d1d46a9d ]

Addresses the following warning when building j2_defconfig:

arch/sh/kernel/cpu/sh2/probe.c: In function 'scan_cache':
arch/sh/kernel/cpu/sh2/probe.c:24:16: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast]
   24 |  j2_ccr_base = (u32 __iomem *)of_flat_dt_translate_address(node);
      |

Fixes: 5a846abad07f ("sh: add support for J-Core J2 processor")
