It should be given the size of the pointed skl_ipc_dxstate_info structure instead. Coincidentally, both the pointer and the structure have the same size of 8 bytes on a 64 bit machine, which "masks" the issue. Compiling for 32 bit reveals the issue more clearly. Fix the typo for correctness, and to make the code robust to future evolutions of the skl_ipc_dxstate_info structure size. This fixes the following coccicheck error: sound/soc/intel/skylake/skl-sst-ipc.c:641:8-14: ERROR: application of sizeof to pointer Signed-off-by: Vincent Stehlé Cc: Subhransu S.
