exactly 4 bytes in size.

of an exposed memory block may be something like 4k.

transformation:

1. Inline wr_reg32 helpers:

if (caam_little_end) {
if (!caam_imx) {

iowrite32be(data, (u32 __iomem *)(reg) + 1);
}

3. Invert the check for !caam_imx:

if (caam_little_end) {
if (caam_imx) {
iowrite32(data >> 32, (u32 __iomem *)(reg));
iowrite32(data, (u32 __iomem *)(reg) + 1);
} else {

}
} else {
iowrite32be(data >> 32, (u32 __iomem *)(reg));
iowrite32be(data, (u32 __iomem *)(reg) + 1);
}

4. Make use of iowrite64* helpers from <linux/io-64-nonatomic-hi-lo.h>

if (caam_little_end) {
if (caam_imx) {
iowrite32(data >> 32, (u32 __iomem *)(reg));
iowrite32(data, (u32 __iomem *)(reg) + 1);
} else {
iowrite64(data, reg);
}
} else {
iowrite64be(data, reg);
}

crypto: s5p - deal gracefully with bogus input sizes

The s5p skcipher driver returns -EINVAL for zero length inputs, which
deviates from the behavior of the generic ECB template, and causes fuzz
tests to fail. In cases where the input is not a multiple of the AES
block size (and the chaining mode is not CTR), it prints an error to
