From: Arnd Bergmann <arnd@xxxxxxxx> When CONFIG_CPUMASK_OFFSTACK is disabled, clang reports a warning about a bogus condition: drivers/crypto/marvell/octeontx2/otx2_cptlf.c:334:21: error: address of array 'lfs->lf[slot].affinity_mask' will always evaluate to 'true' [-Werror,-Wpointer-bool-conversion] if (lfs->lf[slot].affinity_mask) ~~ ~~~~~~~~~~~~~~^~~~~~~~~~~~~ In this configuration, the free_cpumask_var() function does nothing, so the condition could be skipped. When the option is enabled, there is no warning, but the check is also redundant because free_cpumask_var() falls back to kfree(), which is documented as ignoring NULL pointers. Remove the check to avoid the warning.
