kernel 3.x install oss4(open source sound v4.x)

When installing oss modules, the error is

/usr/lib/oss/build/osscore.c: In function ‘oss_get_uid’:

/usr/lib/oss/build/osscore.c:479:3: error: incompatible types when returning type ‘kuid_t’ but ‘unsigned int’ was expected

   return current->cred->uid;

Just edit the file /usr/lib/oss/build/osscore.c then find the method 'oss_get_uid' and then annotate  the line:

#else 
#if LINUX_VERSION_CODE >= KERNEL_VERSION(2,6,29)
  return (unsigned int) (current->cred->uid);
#else
  return (unsigned int) (current->uid);
#endif

and then (enter the directory /usr/lib/oss/build/)

make install
