Hi,
make C=1 in 3.0-rc3 but not in 2.6.39 complains:
CHECK drivers/firewire/ohci.c drivers/firewire/ohci.c:308:1: error: Syntax error in unary expression drivers/firewire/ohci.c:325:1: error: Syntax error in unary expression CC [M] drivers/firewire/ohci.o CHECK drivers/firewire/sbp2.c drivers/firewire/sbp2.c:70:1: error: Syntax error in unary expression drivers/firewire/sbp2.c:116:1: error: Syntax error in unary expression CC [M] drivers/firewire/sbp2.o
These lines are the module_param_named lines of:
static int param_quirks; module_param_named(quirks, param_quirks, int, 0644); MODULE_PARM_DESC(quirks, "Chip quirks (default = 0" [...] static int param_debug; module_param_named(debug, param_debug, int, 0644); MODULE_PARM_DESC(debug, "Verbose logging (default = 0" [...]
and
static int sbp2_param_exclusive_login = 1; module_param_named(exclusive_login, sbp2_param_exclusive_login, bool, 0644); MODULE_PARM_DESC(exclusive_login, "Exclusive login to sbp2 device " [...] static int sbp2_param_workarounds; module_param_named(workarounds, sbp2_param_workarounds, int, 0644); MODULE_PARM_DESC(workarounds, "Work around device bugs (default = 0" [...]
Seen with an older version of sparse (perhaps 0.4.2) and the current from sparse.git (0.4.3 plus 13 commmits).
There is only a single change to the kernel's include/linux/moduleparam.h after v2.6.39, "module: reorder kparam_array to remove alignment padding on 64 bit builds", and that one is apparently not the cause of the noise.
