DEBUG is not actually used as far as I can tell (I am still new to kernel debugging systems to please correct me). There is only a pair of .c and .h files for this small driver. UDC_DEBUG_DUMP is only used twice in the entire kernel-both for if statements. Should we just set it to: #define UDC_DEBUG_DUMP 0 And leave the other 3 lines out?

[PATCH 1/2] staging: gasket: Fix 4 over 80 char warnings
Fix 4 over 80 char warnings by caching long enum values into local
variables.
All enums are only used once inside each function (and once inside
the entire file).

I had to switch from a VM to native and forget to put the git hook in
this repo clone.
Still, after I did, checkpatch complained about trailing white space
after SOFTPWRCTL_SWPE2 |, but not the alignment issue. Fixing the
alignment issue produced no warnings either. :(

Thank you for pointing that out Stefano. That would be a serious issue
with logic.
Just to be sure. Are you looking for this?
switch (priv->rf_type) {
case RF_AL2230:
case RF_AL2230S:
case RF_AIROHA7230:
case RF_VT3226:
case RF_VT3226D0:
case RF_VT3342A0:
ret = vnt_mac_reg_bits_on(priv, MAC_REG_SOFTPWRCTL,
(SOFTPWRCTL_SWPE2 |
SOFTPWRCTL_SWPE3));
if (ret)
return ret;
}

What do you mean exactly by this?
The new code should only return a 0 at the end of the function with the
vnt_mac_reg_bits_off call.
