This warning is seen on 64-bit builds in functions:
'mipi_dbi_typec1_command':
'mipi_dbi_typec3_command_read':
'mipi_dbi_typec3_command':
>> drivers/gpu/drm/tinydrm/mipi-dbi.c:65:20: warning: field width specifier '*' expects argument of type 'int', but argument 5 has type 'size_t {aka long unsigned int}' [-Wformat=]
DRM_DEBUG_DRIVER("cmd=%02x, par=%*ph\n", cmd, len, data); \
^
include/drm/drmP.h:228:40: note: in definition of macro 'DRM_DEBUG_DRIVER'
drm_printk(KERN_DEBUG, DRM_UT_DRIVER, fmt, ##__VA_ARGS__)

>> drivers/gpu/drm/tinydrm/mipi-dbi.c:671:2: note: in expansion of macro 'MIPI_DBI_DEBUG_COMMAND'
MIPI_DBI_DEBUG_COMMAND(cmd, parameters, num);
^~~~~~~~~~~~~~~~~~~~~~
Fix by casting 'len' to int in the macro MIPI_DBI_DEBUG_COMMAND().
There is no chance of overflow.

Fix this warning:
drivers/gpu/drm/tinydrm/mipi-dbi.c: In function ‘mipi_dbi_debugfs_command_write’:
drivers/gpu/drm/tinydrm/mipi-dbi.c:905:8: warning: ‘cmd’ may be used uninitialized in this function [-Wmaybe-uninitialized]
ret = mipi_dbi_command_buf(mipi, cmd, parameters, i);
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
cmd can't be used uninitialized, but to satisfy the compiler,
initialize it to zero.

tinydrm provides helpers for very simple displays that can use
CMA backed framebuffers and need flushing on changes.
