enic: fix build warning without CONFIG_CPUMASK_OFFSTACK
[ Upstream commit 43d281662fdb46750d49417559b71069f435298d ]
The enic driver relies on the CONFIG_CPUMASK_OFFSTACK feature to
dynamically allocate a struct member, but this is normally intended for
local variables.
Building with clang, I get a warning for a few locations that check the
address of the cpumask_var_t:
drivers/net/ethernet/cisco/enic/enic_main.c:122:22: error: address of array 'enic->msix[i].affinity_mask' will always evaluate to 'true' [-Werror,-Wpointer-bool-conversion]
As far as I can tell, the code is still correct, as the truth value of
the pointer is what we need in this configuration. To get rid of
the warning, use cpumask_available() instead of checking the
pointer directly.
