+Subject: ALSA: hda/realtek - Add Dell ALC295 to pin fall back table
+
+From: Kailang Yang <kailang@realtek.com>
+
+commit 4b21a669ca21ed8f24ef4530b2918be5730114de upstream.
+
+Add ALC295 to pin fall back table.
+Remove 5 pin quirks for Dell ALC295.
+ALC295 was only support MIC2 for external MIC function.
+ALC295 assigned model "ALC269_FIXUP_DELL1_MIC_NO_PRESENCE" for pin
+fall back table.
+It was assigned wrong model. So, let's remove it.

+Subject: ALSA: info: Fix potential deadlock at disconnection
+
+From: Takashi Iwai <tiwai@suse.de>
+
+commit c7a60651953359f98dbf24b43e1bf561e1573ed4 upstream.
+
+As reported recently, ALSA core info helper may cause a deadlock at
+the forced device disconnection during the procfs operation.
+
+The proc_remove() (that is called from the snd_card_disconnect()
+helper) has a synchronization of the pending procfs accesses via
+wait_for_completion(). Meanwhile, ALSA procfs helper takes the global
+mutex_lock(&info_mutex) at both the proc_open callback and
+snd_card_info_disconnect() helper. Since the proc_open can't finish
+due to the mutex lock, wait_for_completion() never returns, either,
+hence it deadlocks.
+
+ TASK#1 TASK#2
+ proc_reg_open()
+ takes use_pde()
+ snd_info_text_entry_open()
+ snd_card_disconnect()
+ snd_info_card_disconnect()
+ takes mutex_lock(&info_mutex)
+ proc_remove()
+ wait_for_completion(unused_pde)
+ ... waiting task#1 closes
+ mutex_lock(&info_mutex)
+ => DEADLOCK
+
+This patch is a workaround for avoiding the deadlock scenario above.
+
+The basic strategy is to move proc_remove() call outside the mutex
+lock. proc_remove() can work gracefully without extra locking, and it
+can delete the tree recursively alone. So, we call proc_remove() at
+snd_info_card_disconnection() at first, then delete the rest resources
+recursively within the info_mutex lock.
+
+After the change, the function snd_info_disconnect() doesn't do
+disconnection by itself any longer, but it merely clears the procfs
+pointer. So rename the function to snd_info_clear_entries() for
+avoiding confusion.
+
+The similar change is applied to snd_info_free_entry(), too. Since
+the proc_remove() is called only conditionally with the non-NULL
+entry->p, it's skipped after the snd_info_clear_entries() call.
