Subject: RDMA/mthca: Make explicit conversion to 64bit value
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=623248955d985b86cd778c63efe6a7ad03a018c4;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

RDMA/mthca: Make explicit conversion to 64bit value

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/infiniband/hw/mthca/mthca_cmd.c:701 mthca_map_cmd() warn:
	should '1 << lg' be a 64 bit type?

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