In this patch SGX powervr_device is registered with it's platform specific
data to provide information about setting constraint through
omap_pm_set_min_bus_tput.
This patch removes the requirement of EXPORT_SYMBOL for the same function.

you shouldn't add my signed-off-by unless I explicitly tell you it's ok
to do so :-)

won't this break when !CONFIG_PM ??

not here... the platform_data should always exist otherwise this won't
compile. See that struct sgx_platform_data doesn't even exist if
!CONFIG_PM and you still instantiate a variable of that type
unconditionaly. I suggest you use:
header:
struct sgx_platform_data {
void (*set_pm_constraints)(struct device *dev, u8 agent_id,
};
C-source:
#ifdef CONFIG_PM
static void omap_sgx_pm_constraints(struct device *dev, u8 agent_id,
unsigned long r)
{
omap_pm_set_min_bus_tput(dev, agent_id, r);
}
#else
static inline void omap_sgx_pm_constraints(struct device *dev,
u8 agent_id, unsigned long r)
{ }
#endif
struct sgx_platform_data omap_sgx_data = {
.set_pm_constraints = omap_sgx_pm_constraints,
};
static struct platform_device powervr_device = {
.name = "pvrsrvkm",
.id = -1,
.dev = {
.platform_data = &omap_sgx_data,
},
};
