    Subject3.0-rc3: new sparse noise on module_param_named: "error: Syntax error in unary expression"
    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.

    Puzzled,
