Add missing check in the kb3930_probe().\nThis is similar to the issue fixed in commit b1ba8bcb2d1f\n("backlight: hx8357: Fix potential NULL pointer dereference").\n\nThis was detected by our static analysis tool.(CVE-2025-23146)\n\nIn the Linux kernel, the following vulnerability has been resolved:\n\njbd2: remove wrong sb->s_sequence check\n\nJournal emptiness is not determined by sb->s_sequence == 0 but rather by\nsb->s_start == 0 (which is set a few lines above). Furthermore 0 is a\nvalid transaction ID so the check can spuriously trigger. Remove the\ninvalid WARN_ON.(CVE-2025-37839)\n\nIn the Linux kernel, bit_putcs_aligned()/unaligned() derived the glyph pointer from the character value masked by 0xff/0x1ff, which may exceed the actual font's glyph count and read past the end of the built-in font array. Clamp the index to the actual glyph count before computing the address.
