Fork of alistair23 Linux kernel for reMarkable from https://github.com/alistair23/linux

Clang warns when one enumerated type is implicitly converted to another
and this happens in several locations in this driver, ultimately related
to the set_cipher_{mode,config0} functions. set_cipher_mode expects a mode
of type drv_cipher_mode and set_cipher_config0 expects a mode of type
drv_crypto_direction.
drivers/crypto/ccree/cc_ivgen.c:58:35: warning: implicit conversion from
enumeration type 'enum cc_desc_direction' to different enumeration type
'enum drv_crypto_direction' [-Wenum-conversion]
set_cipher_config0(&iv_seq[idx], DESC_DIRECTION_ENCRYPT_ENCRYPT);
drivers/crypto/ccree/cc_hash.c:99:28: warning: implicit conversion from
enumeration type 'enum cc_hash_conf_pad' to different enumeration type
'enum drv_crypto_direction' [-Wenum-conversion]
set_cipher_config0(desc, HASH_DIGEST_RESULT_LITTLE_ENDIAN);
drivers/crypto/ccree/cc_aead.c:1643:30: warning: implicit conversion
from enumeration type 'enum drv_hash_hw_mode' to different enumeration
type 'enum drv_cipher_mode' [-Wenum-conversion]
set_cipher_mode(&desc[idx], DRV_HASH_HW_GHASH);
Since this fundamentally isn't a problem because these values just
represent simple integers for a shift operation, make it clear to Clang
that this is okay by making the mode parameter in both functions an int.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
