Subject: [PATCH] crypto: caam/qi - fix compilation with DEBUG enabled
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
References: bnc#1060662
Patch-mainline: 4.12.12
Git-commit: 972b812bd1e17cb0a9112f565951795f886fcc94
commit 972b812bd1e17cb0a9112f565951795f886fcc94 upstream.
caam/qi driver does not compile when DEBUG is enabled
(CRYPTO_DEV_FSL_CAAM_DEBUG=y):
drivers/crypto/caam/caamalg_qi.c: In function 'ablkcipher_done':
drivers/crypto/caam/caamalg_qi.c:794:2: error: implicit declaration of function 'dbg_dump_sg' [-Werror=implicit-function-declaration]
dbg_dump_sg(KERN_ERR, "dst @" __stringify(__LINE__)": ",
Since dbg_dump_sg() is shared between caam/jr and caam/qi, move it
in a shared location and export it.
At the same time:
-reduce ifdeferry by providing a no-op implementation for !DEBUG case
-rename it to caam_dump_sg() to be consistent in terms of
exported symbols namespace (caam_*)
