From e620a1e061c4738e26c3edf2abaae7842532cd80 Mon Sep 17 00:00:00 2001 From: Stephen Kitt Date: Fri, 27 Sep 2019 20:51:10 +0200 Subject: [PATCH] drivers/clk: convert VL struct to struct_size There are a few manually-calculated variable-length struct allocations left, this converts them to use struct_size. Found with the following git grep command git grep -A1 'kzalloc.*sizeof[^_].*+' Signed-off-by: Stephen Kitt Link: https://lkml.kernel.org/r/20190927185110.29897-1-steve@sk2.org Acked-by: Gustavo A.
