ssi->port is no longer dynamically allocated, so there is now a warning
from clang about the check being always true:
drivers/hsi/controllers/omap_ssi_port.c:1121:12: error: address of array 'ssi->port' will always evaluate to 'true' [-Werror,-Wpointer-bool-conversion]
1121 | if (!ssi->port || !omap_ssi->port) {
Remove it, as was done in the hsi core code.
Fixes: e61af3ca8933 ("hsi: hsi_core: use kzalloc_flex")

Whichever makes it in is fine with me.
