mainline build failure due to 8bdc2a190105 ("crypto: poly1305 - cleanup stray CRYPTO_LIB_POLY1305_RSIZE")

Hi All,

The latest mainline kernel branch fails to build for:

arm: imx_v6_v7_defconfig and multi_v7_defconfig
mips: decstation_64_defconfig, decstation_defconfig, decstation_r4k_defconfig

with errors like:

In file included from crypto/chacha20poly1305.c:13:
./include/crypto/poly1305.h:56:46: error: 'CONFIG_CRYPTO_LIB_POLY1305_RSIZE' undeclared here (not in a function); did you mean 'CONFIG_CRYPTO_POLY1305_MODULE'?
   56 |                 struct poly1305_key opaque_r[CONFIG_CRYPTO_LIB_POLY1305_RSIZE];
      |                                              ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~


git bisect pointed to 8bdc2a190105 ("crypto: poly1305 - cleanup stray CRYPTO_LIB_POLY1305_RSIZE")

I have checked .config to confirm that it contains:

CONFIG_CRYPTO_CHACHA20POLY1305=m
# CONFIG_CRYPTO_LIB_POLY1305 is not set

so, CONFIG_CRYPTO_LIB_POLY1305_RSIZE will not be defined as it now
depends on CONFIG_CRYPTO_LIB_POLY1305.
