commit 5ee7d4c7fbc9d3119a20b1c77d34003d1f82ac26 upstream.

gcc-11 complains about a prototype declaration that is different
from the function definition:

drivers/isdn/capi/kcapi.c:724:44: error: argument 2 of type ‘u8 *’ {aka ‘unsigned char *’} declared as a pointer [-Werror=array-parameter=]
  724 | u16 capi20_get_manufacturer(u32 contr, u8 *buf)
      |                                        ~~~~^~~

Change the definition to make them match.
