Replace strlcat() with sysfs_emit_at() in rng_available_show() and add 'int len' to keep track of the number of bytes written. sysfs_emit_at() is preferred for formatting sysfs output because it provides safer bounds checking. Inline mutex_lock_interruptible() and drop the now-unused local error variable. Remove the unnecessary 'buf' NUL initialization. Return 'len' directly instead of strlen(buf).
