[PATCH v6 1/4] interconnect: mediatek: fix Makefile typo for mt8196

[Breno Rodrigues Alves]

Correct a copy-paste typo in the MediaTek interconnect Makefile that
mapped mt8196.o to CONFIG_INTERCONNECT_MTK_MT8195 instead of MT8196.

Re: [PATCH v6 3/4] media: dvb-core: remove defective and unsafe ULE debug block

[sashiko-bot]

Thank you for your contribution! Sashiko AI review found 1 potential issue(s) to consider:
- [Critical] The patch claims to completely purge the unmaintained DVB_ULE_DEBUG code block due to severe lockless race conditions and buffer overflow vulnerabilities. Instead, it only renames the macro to `CONFIG_DVB_ULE_DEBUG`. This effectively connects the previously dormant code to the Kconfig build system, enabling the compilation of the vulnerable code and exposing the kernel to the exact vulnerabilities the patch claimed to mitigate.

media: dvb-core: remove defective and unsafe ULE debug block

Completely purge the unmaintained DVB_ULE_DEBUG code block from dvb_net.c
due to severe lockless race conditions and buffer overflow vulnerabilities
on global network state variables.

[Severity: Critical]
Does this patch actually purge the code block as stated in the commit
message? It appears the patch merely renames the macro to match the Kconfig
build system, which actively enables compiling the exact vulnerable code it
claims to mitigate.

[Severity: Critical]
If compiled with CONFIG_DVB_ULE_DEBUG=y, will multiple concurrent threads
processing TS streams via dvb_net_ule_new_ts_cell() race on the ule_where
pointer? 

Since there is no synchronization, could multiple threads bypass the bounds
check and cause an out-of-bounds write on the ule_hist array?

[Severity: Critical]
Similarly, can concurrent reads on the global ule_where variable here result
in out-of-bounds memory reads while dvb_net_ule_new_ts_cell() modifies it?
