74c0a6d16d drivers: Drop inline from driver remove wrapper 
The driver remove function is a function pointer and therefore, it does
not make sense to define the function as an 'inline'. Update the
coccinelle script and drivers to remove the inline statement.

as necessary to fix this.

cdc64f43fa drivers: Drop version check for DMA BUF namespace 
The MODULE_IMPORT_NS macro adds a namespace tag to the module
information. The DMA_BUF namespace is required for Linux v5.16+ kernels
for drivers that use DMA BUF, there is no reason not to populate this
for earlier kernels. Furthermore, some 3rd party kernels prior to v5.16
may require this too and so drop the version check around the DMA BUF
namespace.

74b186dc9e drivers: pva: Fix compilation error 
When building the PVA driver with GCC 13 the following error is
observed ...

 drivers/video/tegra/host/pva/pva.c:1366:13:
  error: the comparison will always evaluate as ‘true’ for the address
  of ‘clk_cap_kobj’ will never be NULL [-Werror=address]
 1366 |         if (&pdata->clk_cap_kobj) {
      |             ^

The 'clk_cap_kobj' member of 'nvhost_device_data' structure is not a
pointer to a structure but a structure and so the address of the
structure is always true. Fix this by testing if the address of the
'clk_cap_attrs' member which is a pointer to memory that is
allocated.

3ee67f0ee5 host1x: do not use CONFIG_TEGRA_SOC_HWPM 
OOT kerel builds do not use Kconfig files to define required
config flags. Thus, CONFIG_TEGRA_SOC_HWPM is not defined for OOT
configs. Remove use of CONFIG_TEGRA_SOC_HWPM flag from PVA, DLA
and FLCN drivers.

For OOT builds, HWPM driver is always compiled independent of
CONFIG_TEGRA_SOC_HWPM flag. For safety builds where HWPM
functionality is not allowed, mock HWPM functions will be used.
