x86/cpu/intel_cacheinfo: Remove redundant assignment to 'this_leaf'
The 'this_leaf' variable is assigned a value that is never read and it is updated a little later with a newer value, hence we can remove the redundant assignment. Cleans up the following Clang warning: Value stored to 'this_leaf' is never read Signed-off-by: Colin Ian King <colin.king@canonical.com> Reviewed-by: Borislav Petkov <bp@suse.de> Cc: Linus Torvalds <torvalds@linux-foundation.org> Cc: Peter Zijlstra <peterz@infradead.org> Cc: Thomas Gleixner <tglx@linutronix.de> Cc: kernel-janitors@vger.kernel.org Link: http://lkml.kernel.org/r/20171015160203.12332-1-colin.king@canonical.com Signed-off-by: Ingo Molnar <mingo@kernel.org>
