Re: [PATCH 1/4] crypto: sunxi - don't print uninitialized data

gcc correctly warns that the printk output contains a variable that
is not initialized in some cases:

drivers/crypto/sunxi-ss/sun4i-ss-cipher.c: In function 'sun4i_ss_cipher_poll':
drivers/crypto/sunxi-ss/sun4i-ss-cipher.c:254:76: warning: 'todo' may be used uninitialized in this function [-Wmaybe-uninitialized]
drivers/crypto/sunxi-ss/sun4i-ss-cipher.c:144:15: note: 'todo' was declared here

This adds an explicit initialization to zero in the exact case where it
was missing, to avoid leaking stack data to the console and to shut up
that warning.

Sorry for the broken ordering and missing cover letter. 
I just submitted three crypto patches:

[PATCH 1/4] crypto: sunxi - don't print uninitialized data
[PATCH] crypto: hash - select CRYPTO_HASH where needed
[PATCH 1/2] crypto: jitterentropy - always select CRYPTO_RNG

These address independent build issues, and there is no ordering between
them. None of them are important, so please queue them up for 4.6.
