With a later commit an instance of the struct device will be added to struct genpd and with that the size of the struct tegra_powergate will be over 1024 bytes. That generates following warning: drivers/soc/tegra/pmc.c:579:1: warning: the frame size of 1200 bytes is larger than 1024 bytes [-Wframe-larger-than=] Avoid such warnings by allocating the structure dynamically. Signed-off-by: Viresh Kumar <viresh.kumar@xxxxxxxxxx> --- V2: - Based of latest changes. - Compile tested only. @Jon: This was sent long back[1], but then the genpd series wasn't finalized, which is going to get merged [2] very soon now. Can I have your Ack for this patch so that I can apply it at the beginning of that series ?
