Subject[PATCH 5.9 478/757] overflow: Include header file with SIZE_MAX declaration
Date
From: Leon Romanovsky <leonro@nvidia.com>

[ Upstream commit a4947e84f23474803b62a2759b5808147e4e15f9 ]

The various array_size functions use SIZE_MAX define, but missed limits.h
causes to failure to compile code that needs overflow.h.

In file included from drivers/infiniband/core/uverbs_std_types_device.c:6:
./include/linux/overflow.h: In function 'array_size':
./include/linux/overflow.h:258:10: error: 'SIZE_MAX' undeclared (first use in this function)
258 | return SIZE_MAX;
| ^~~~~~~~

Fixes: 610b15c50e86 ("overflow.h: Add allocation size calculation helpers")
