Subject: [PATCH] x86/platform/olpc: Fix not used variable 'len'

Fix the following compilation warning:

arch/x86/platform/olpc/olpc_dt.c: In function ‘olpc_dt_compatible_match’:
arch/x86/platform/olpc/olpc_dt.c:222:12: warning: variable ‘len’ set but
not used [-Wunused-but-set-variable]
  222 |  int plen, len;

The local variable len is set but never used, so remove it.

Fixes: a7a9bacb9a32 ("x86/platform/olpc: Use a correct version when making up a battery node")
