[ Upstream commit b76e0d4215b6b622127ebcceaa7f603313ceaec4 ] _be32 type is defined for some elements in pseries_hp_errorlog struct but also used them u32 after be32_to_cpu() conversion. Example: In handle_dlpar_errorlog() hp_elog->_drc_u.drc_index = be32_to_cpu(hp_elog->_drc_u.drc_index); And later assigned to u32 type dlpar_cpu() - u32 drc_index = hp_elog->_drc_u.drc_index; This incorrect usage is giving the following warnings and the patch resolve these warnings with the correct assignment. arch/powerpc/platforms/pseries/dlpar.c:398:53: sparse: sparse: incorrect type in argument 1 (different base types) @@ expected unsigned int [usertype] drc_index @@ got restricted __be32 [usertype] drc_index @@ ... arch/powerpc/platforms/pseries/dlpar.c:418:43: sparse: sparse: incorrect type in assignment (different base types) @@ expected restricted __be32 [usertype] drc_count @@ got unsigned int [usertype] @@ Reported-by: kernel test robot <lkp@intel.com> Closes: https://lore.kernel.org/oe-kbuild-all/202408182142.wuIKqYae-lkp@intel.com/ Closes: https://lore.kernel.org/oe-kbuild-all/202408182302.o7QRO45S-lkp@intel.com/ Signed-off-by: Haren Myneni <haren@linux.ibm.com> v3: - Fix warnings from using incorrect data types in pseries_hp_errorlog struct v2: - Remove pr_info() and TODO comments - Update more information in the commit logs Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> Link: https://msgid.link/20240822025028.938332-1-haren@linux.ibm.com Signed-off-by: Sasha Levin <sashal@kernel.org>
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.
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.
