Subject: [PATCH 0/7] crypto: Proper Initialization of `struct skcipher_walk` in x86 Glue Files

In multiple `*_encrypt`, `*_crypt`, `*_decrypt` functions within the x86/crypto
glue files, the `skcipher_walk` structs being used are not properly initialized
prior their usage which can lead to undefined behaviour if the `flags` field of
this structure were to contain junk values at the time of its usage.

This patch series ensures that instances of `struct skcipher_walk` are correctly
initialized across different x86/crypto glue files.

Yuran Pereira (7):
  crypto: Fixes uninitialized skcipher_walk use in sm4_aesni_avx_glue
  crypto: Fixes uninitialized skcipher_walk use in des3_ede_glue
  crypto: Fixes uninitialized skcipher_walk use in chacha_glue
  crypto: Fixes uninitialized skcipher_walk use in aesni-intel_glue
  crypto: Fixes uninitialized skcipher_walk use in aria_aesni_avx2_glue
  crypto: Fixes uninitialized skcipher_walk use in aria_aesni_avx_glue
  crypto: Fixes uninitialized skcipher_walk use in aria_gfni_avx512_glue
