[PATCH 3.2 26/61] net/mlx4_core: Make explicit conversion to 64bit value

[Ben Hutchings]

3.2.96-rc1 review patch.  If anyone has any objections, please let me know.

------------------

From: Leon Romanovsky <leonro@xxxxxxxxxxxx>

commit 187782eb58a89ea030731114c6ae37842a4472fe upstream.

The "lg" variable is declared as int so in all places where this variable
is used as a shift operand, the output will be int too.

This produces the following smatch warning:
drivers/net/ethernet/mellanox/mlx4/fw.c:1532 mlx4_map_cmd() warn:
	should '1 << lg' be a 64 bit type?

Simple declaration of "1" to be "1ULL" will fix the issue.
