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)
| ~~~~^~~
In file included from drivers/isdn/capi/kcapi.c:13:
drivers/isdn/capi/kcapi.h:62:43: note: previously declared as an array ‘u8[64]’ {aka ‘unsigned char[64]’}
62 | u16 capi20_get_manufacturer(u32 contr, u8 buf[CAPI_MANUFACTURER_LEN]);
| ~~~^~~~~~~~~~~~~~~~~~~~~~~~~~
drivers/isdn/capi/kcapi.c:790:38: error: argument 2 of type ‘u8 *’ {aka ‘unsigned char *’} declared as a pointer [-Werror=array-parameter=]

Change the definition to make them match.
