[Xenomai-core] Problems with compat_module_param_array() with Linux 2.4

[Wolfgang Grandegger <wg@domain.hid>]

Hello,

yesterday I realized a problem with compat_module_param_array() with
ksrc/drivers/can/sja1000/rtcan_mem.c under Linux 2.4. It uses
CONFIG_XENO_DRIVERS_CAN_SJA1000_MEM_MAX_DEV to define the number of mem
devices, which is set to '(4)' by "make [menuc]onfig". Unfortunately, 
the brackets '()' break compat_module_param_array() because it treats 
the count as string:

#define compat_module_param_array(name, type, count, perm) \
         static inline void *__check_existence_##name(void) { return
&name; } \
         MODULE_PARM(name, "1-" __MODULE_STRING(count)
_MODULE_PARM_STRING_##type)

Any idea how to fix that? I actually tend to remove the configuration 
option CONFIG_XENO_DRIVERS_CAN_SJA1000_MEM_MAX_DEV and hardcode it to 
"4" (without brackets) in the driver. It's kind of overkill, anyhow.

Wolfgang.
