[parted-devel] [PATCH 01/24] libparted: Fix a GCC warning -Wunused-but-set-variable

[Brian C. Lane]

From: Shin'ichiro Kawasaki <kawasaki at juno.dti.ne.jp>

GCC warns that a variable 'prealloc' defined for _generic_affs_probe() in
fs/amiga/affs.c is set but its value is never used.

  CC       amiga/affs.lo
amiga/affs.c: In function '_generic_affs_probe':
amiga/affs.c:54:35: warning: variable 'prealloc' set but not used [-Wunused-but-set-variable]
   54 |  int blocksize = 1, reserved = 2, prealloc = 0;
      |                                   ^~~~~~~~
Remove the variable for simplicity and to avoid the warning.
