Browse Source 
Fixes build error with -Werror:

shm/shmfs.c: In function 'shmfs_read':
shm/shmfs.c:122:33: error: pointer of type 'void *' used in arithmetic [-Werror=pointer-arith]
  122 |       memcpy(buffer, sho->paddr + startpos, nread);
      |                                 ^
shm/shmfs.c: In function 'shmfs_write':
shm/shmfs.c:166:25: error: pointer of type 'void *' used in arithmetic [-Werror=pointer-arith]
  166 |       memcpy(sho->paddr + startpos, buffer, nwritten);
      |                         ^
