checkpatch: CHECK: No space is necessary after a cast

[Marek Lindner]

Hi Joe,

we have come across a checkpatch false-positive:

>>>>
static void batadv_recv_handler_init(void)
{
        int i;

        for (i = 0; i < ARRAY_SIZE(batadv_rx_handler); i++)
                batadv_rx_handler[i] = batadv_recv_unhandled_packet;

        for (i = BATADV_UNICAST_MIN; i <= BATADV_UNICAST_MAX; i++)
                batadv_rx_handler[i] = batadv_recv_unhandled_unicast_packet;

        /* compile time checks for sizes */
        BUILD_BUG_ON(sizeof(struct batadv_bla_claim_dst) != 6);
        BUILD_BUG_ON(sizeof(struct batadv_ogm_packet) != 24);
        BUILD_BUG_ON(sizeof(struct batadv_icmp_header) != 20);
        ..
}
<<<<<

The following warnings are triggered:

CHECK: No space is necessary after a cast
#440: FILE: main.c:440:
+       BUILD_BUG_ON(sizeof(struct batadv_bla_claim_dst) != 6);

CHECK: No space is necessary after a cast
#441: FILE: main.c:441:
+       BUILD_BUG_ON(sizeof(struct batadv_ogm_packet) != 24);

CHECK: No space is necessary after a cast
#442: FILE: main.c:442:
+       BUILD_BUG_ON(sizeof(struct batadv_icmp_header) != 20);

Can you make a suggestion / patch for checkpatch to better handle this case ?

Thanks,
Marek
