gcc correctly warns that the printk output contains a variable that it thinks 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 A closer look at the function reveals that the variable is always initialized at this point (ileft is guaranteed to be positive at the start), but its contents are not well-defined: Depending on some other variables, it might be either a count in words or bytes, and it could refer to either input or output. The easiest solution apparently is to remove the confusing output and let the reader figure out the state from the other variables.
