[PATCH AUTOSEL 5.13 068/114] ALSA: control_led - fix initialization in the mode show callback

From: Jaroslav Kysela <perex(a)perex.cz> [ Upstream commit e381a14c3e3a4e90e293d4eaa5a3ab8ae98b9973 ] The str variable should be always initialized before use even if the switch covers all cases.

[PATCH AUTOSEL 5.13 063/114] ALSA: sb: Fix potential double-free of CSP mixer elements

From: Takashi Iwai <tiwai(a)suse.de> [ Upstream commit c305366a37441c2ac90b08711cb6f032b43672f2 ] snd_sb_qsound_destroy() contains the calls of removing the previously created mixer controls, but it doesn't clear the pointers.

[PATCH AUTOSEL 5.13 023/114] Revert "ALSA: bebob/oxfw: fix Kconfig entry for Mackie d.2 Pro"
by Sasha Levin 10 Jul '21

10 Jul '21

From: Takashi Sakamoto <o-takashi(a)sakamocchi.jp> [ Upstream commit 5d6fb80a142b5994355ce675c517baba6089d199 ] This reverts commit 0edabdfe89581669609eaac5f6a8d0ae6fe95e7f. I've explained that optional FireWire card for d.2 is also built-in to d.2 Pro, however it's wrong. The optional card uses DM1000 ASIC and has 'Mackie DJ Mixer' in its model name of configuration ROM. On the other hand, built-in FireWire card for d.2 Pro and d.4 Pro uses OXFW971 ASIC and has 'd.Pro' in its model name according to manuals and user experiences. The former card is not the card for d.2 Pro. They are similar in appearance but different internally.

[PATCH AUTOSEL 5.13 022/114] ALSA: usx2y: Don't call free_pages_exact() with NULL address
by Sasha Levin 10 Jul '21

10 Jul '21

From: Takashi Iwai <tiwai(a)suse.de> [ Upstream commit cae0cf651adccee2c3f376e78f30fbd788d0829f ] Unlike some other functions, we can't pass NULL pointer to free_pages_exact(). Add a proper NULL check for avoiding possible Oops.
