Analyze and fix the following issue in the Linux kernel code: phy/rockchip: inno-hdmi: round fractal pixclock in rk3328 recalc_rate
Problem Details: inno_hdmi_phy_rk3328_clk_recalc_rate() is returning a rate not found in the pre pll config table when the fractal divider is used. This can prevent proper power_on because a tmdsclock for the new rate is not found in the pre pll config table. Fix this by saving and returning a rounded pixel rate that ...

Analyze and fix the following issue in the Linux kernel code: erofs: fix fsdax unavailability for chunk-based regular files
Problem Details: DAX can be used to share page cache between VMs, reducing guest memory overhead. And chunk based data format is widely used for VM and container image. So enable dax support for it, make erofs better used for VM scenarios. Fixes: c5aa903a59db ("erofs: support reading chunk-based uncompressed files") S...

Problem Details: z_erofs_do_read_page() may loop infinitely due to the inappropriate truncation in the below statement. Since the offset is 64 bits and min_t() truncates the result to 32 bits.
