2024-10-04drivers: media: dvb-frontends/rtl2830: fix an out-of-bounds write errorJunlin Li1-1/+1
[ Upstream commit 46d7ebfe6a75a454a5fa28604f0ef1491f9d8d14 ] Ensure index in rtl2830_pid_filter does not exceed 31 to prevent out-of-bounds access. dev->filters is a 32-bit value, so set_bit and clear_bit functions should only operate on indices from 0 to 31. If index is 32, it will attempt to access a non-existent 33rd bit, leading to out-of-bounds access. Change the boundary check from index > 32 to index >= 32 to resolve this issue.

2024-06-16media: mxl5xx: Move xpt structures off stackNathan Chancellor1-11/+11
commit 526f4527545b2d4ce0733733929fac7b6da09ac6 upstream. When building for LoongArch with clang 18.0.0, the stack usage of probe() is larger than the allowed 2048 bytes: drivers/media/dvb-frontends/mxl5xx.c:1698:12: warning: stack frame size (2368) exceeds limit (2048) in 'probe' [-Wframe-larger-than] 1698 | static int probe(struct mxl *state, struct mxl5xx_cfg *cfg) | ^ 1 warning generated. This is the result of the linked LLVM commit, which changes how the arrays of structures in config_ts() get handled with CONFIG_INIT_STACK_ZERO and CONFIG_INIT_STACK_PATTERN, which causes the above warning in combination with inlining, as config_ts() gets inlined into probe(). This warning can be easily fixed by moving the array of structures off of the stackvia 'static const', which is a better location for these variables anyways because they are static data that is only ever read from, never modified, so allocating the stack space is wasteful. This drops the stack usage from 2368 bytes to 256 bytes with the same compiler and configuration.

In commit 9011e49d54dc ("modules: only allow symbol_get of EXPORT_SYMBOL_GPL modules") the use of symbol_get is properly restricted to GPL-only marked symbols. This interacts oddly with the DVB logic which only uses dvb_attach() to load the dvb driver which then uses symbol_get(). Fix this up by properly marking all of the dvb_attach attach symbols as EXPORT_SYMBOL_GPL().

2023-07-19media: Explicitly include correct DT includesRob Herring1-1/+1
The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it as merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree. In order to detangle these headers and replace the implicit includes with struct declarations, users need to explicitly include the correct includes.

2022-11-25media: dvb-frontends: a8293: fix LNB powerup failure in PCTV 461eChuck Ritola2-3/+155
Fixes a8293 failure to raise LNB voltage in PCTV 461e DVB-S2 Stick affecting multiple users over several years as found here: http://www.linuxquestions.org/questions/linux-hardware-18/pctv-dvb-s2-stick-461e-not-feeding-lnb-4175529374/ https://www.linuxtv.org/wiki/index.php/Pinnacle_PCTV_DVB-S2_Stick_(461e) https://github.com/OpenELEC/OpenELEC.tv/issues/3731 Caused by vIN undervoltage lockout (status register bit 7) when raising LNB to 18V. Addressed by using the higher-precision voltages available on the a8293 to gradually increase (slew) the voltage when voltage increases are requested. Adds volt_slew_nanos_per_mv to a8293_platform_data struct for specifying slew rate. If value is <1 or non-sane (>1600), the original no-slew version for a8293_set_voltage is used.
