Updated single and double quotes throughout

alsa-project/alsa-utils pull request #215 was opened from wileyhy: This commit: - Added double quotes to common expansions; removed quotes from strings; - Changed REQUIRES to an indexed array and changed the corresponding for loop; - Added curly braces where feasibly necessary; - Removed a few unnecessary trailing semi-colons; - Put URL's in single quotes to prevent any possible expansions, except for within the sed command on line 988. - Some logic structures may depend on word splitting, on lines 641, 643, 654, and 667, so I left those as-is for this commit. - Double exclamation marks in double quotes allow history expansion which is usually disabled in non-interactive shells, so I left those as-is also. - Single quoted instances of 'yes' as a parameter value, since it's also a command name, which in certain contexts could be executed. - Removed quotes from instances of '$?' since it can only expand to an integer and cannot be unset. Some additional issues for consideration of further efforts (credit: shellcheck): - variables 'inp' on line 87 and 'KERNEL_RELEASE' on line 418 appear unused; - https://pastebin.ca is offline Request URL : https://github.com/alsa-project/alsa-utils/pull/215 Patch URL : https://github.com/alsa-project/alsa-utils/pull/215.patch Repository URL: https://github.com/alsa-project/alsa-utils

[PATCH v2][next] ALSA: mixart: Replace one-element arrays with simple object declarations
by Gustavo A. R. Silva 20 May '23

20 May '23

One-element arrays are deprecated, and we are replacing them with flexible array members instead. However, in this case it seems those one-element arrays have never actually been used as fake flexible arrays. See this code that dates from Linux-2.6.12-rc2 initial git repository build (commit 1da177e4c3f4 ("Linux-2.6.12-rc2")): sound/pci/mixart/mixart_core.h: 215 struct mixart_stream_state_req 216 { 217 u32 delayed; 218 u64 scheduler; 219 u32 reserved4np[3]; 220 u32 stream_count; /* set to 1 for instance */ 221 struct mixart_flow_info stream_info; /* could be an array[stream_count] */ 222 } __attribute__((packed)); sound/pci/mixart/mixart.c: 388 389 memset(&stream_state_req, 0, sizeof(stream_state_req)); 390 stream_state_req.stream_count = 1; 391 stream_state_req.stream_info.stream_desc.uid_pipe = stream->pipe->group_uid; 392 stream_state_req.stream_info.stream_desc.stream_idx = stream->substream->number; 393 So, taking the code above as example, replace multiple one-element arrays with simple object declarations, and refactor the rest of the code, accordingly. This helps with the ongoing efforts to tighten the FORTIFY_SOURCE routines on memcpy() and help us make progress towards globally enabling -fstrict-flex-arrays=3 [1]. This results in no differences in binary output.

Hey list, I've noticed the following crash since the last few days, causing audio to no longer to work. It could be related to me updating the firmware (bios) not too long ago (I load Mac OS every few months via an external drive) which caused the firmware to be updated. Or, it was a kernel update, that came along every few weeks. I'll try to find my archlinux bugzilla stuff, to report it there as well, but I don't think they are actively patching the sound stuff. The last commit I'm seeing on `patch_cirrus.c` seems to be from aug 2022, so that can't be it, though incidentally, the change is with regards to support for iMac 12,1 model, which is interesting as the number is the same. I understand you guys probably get tons of bug reports, but best to leave it here, just in case.
