   4 Subject: [PATCH 07/15] crypto: crypto4xx - Fix wrong
   5  ppc4xx_trng_probe()/ppc4xx_trng_remove() arguments
   6
   7 When building without CONFIG_HW_RANDOM_PPC4XX, I hit the following build failure:
   8 drivers/crypto/amcc/crypto4xx_core.c: In function 'crypto4xx_probe':
   9 drivers/crypto/amcc/crypto4xx_core.c:1407:20: error: passing argument 1 of 'ppc4xx_trng_probe' from incompatible pointer type [-Werror=incompatible-pointer-types]

  11 drivers/crypto/amcc/crypto4xx_trng.h:28:20: note: expected 'struct crypto4xx_device *' but argument is of type 'struct crypto4xx_core_device *'
  12 drivers/crypto/amcc/crypto4xx_core.c: In function 'crypto4xx_remove':
  13 drivers/crypto/amcc/crypto4xx_core.c:1434:21: error: passing argument 1 of 'ppc4xx_trng_remove' from incompatible pointer type [-Werror=incompatible-pointer-types]

  16
  17 This patch fix the needed argument of ppc4xx_trng_probe()/ppc4xx_trng_remove() in that case.
