apm821xx: Revert upstream fix which breaks compile
This reverts a commit added in kernel v4.4.179 which breaks compilation on the apm821xx target. This fixes the following compile problem: drivers/crypto/amcc/crypto4xx_core.c: In function 'crypto4xx_ablkcipher_done': drivers/crypto/amcc/crypto4xx_core.c:650:21: warning: dereferencing 'void *' pointer if (pd_uinfo->sa_va->sa_command_0.bf.save_iv == SA_SAVE_IV) { ^ drivers/crypto/amcc/crypto4xx_core.c:650:21: error: request for member 'sa_command_0' in something not a structure or union drivers/crypto/amcc/crypto4xx_core.c:651:38: error: implicit declaration of function 'crypto_skcipher_reqtfm' [-Werror=implicit-function-declaration] struct crypto_skcipher *skcipher = crypto_skcipher_reqtfm(req); ^ drivers/crypto/amcc/crypto4xx_core.c:651:61: error: 'req' undeclared (first use in this function) struct crypto_skcipher *skcipher = crypto_skcipher_reqtfm(req); ^ drivers/crypto/amcc/crypto4xx_core.c:651:61: note: each undeclared identifier is reported only once for each function it appears in drivers/crypto/amcc/crypto4xx_core.c:653:3: error: implicit declaration of function 'crypto4xx_memcpy_from_le32' [-Werror=implicit-function-declaration] crypto4xx_memcpy_from_le32((u32 *)req->iv, ^ drivers/crypto/amcc/crypto4xx_core.c:654:19: warning: dereferencing 'void *' pointer pd_uinfo->sr_va->save_iv, ^ drivers/crypto/amcc/crypto4xx_core.c:654:19: error: request for member 'save_iv' in something not a structure or union drivers/crypto/amcc/crypto4xx_core.c:655:4: error: implicit declaration of function 'crypto_skcipher_ivsize' [-Werror=implicit-function-declaration] crypto_skcipher_ivsize(skcipher)); ^ cc1: some warnings being treated as errors Fixes: 6c5c3a2edccf ("kernel: Update to version 4.4.182") Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de>
