sbi->s_freeinodes_counter is only decreased by the ext2 code, it is never increased. This patch fixes it. Note that sbi->s_freeinodes_counter is only used in the algorithm that tries to find the group for new allocations, so this bug is not easily visible (the only visibility is that the group finding algorithm selects inoptinal result).

Almost all callers of ext2_find_entry() transform NULL return value to -ENOENT, so just let ext2_find_entry() retuen -ENOENT instead of NULL if no valid entry found, and also switch to check the return value of ext2_inode_by_name() in ext2_lookup() and ext2_get_parent().

I realize that we fairly recently raised it to 4.8, but the fact is, 4.9 is a much better minimum version to target. We have a number of workarounds for actual bugs in pre-4.9 gcc versions (including things like internal compiler errors on ARM), but we also have some syntactic workarounds for lacking features. In particular, raising the minimum to 4.9 means that we can now just assume _Generic() exists, which is likely the much better replacement for a lot of very convoluted built-time magic with conditionals on sizeof and/or __builtin_choose_expr() with same_type() etc. Using _Generic also means that you will need to have a very recent version of 'sparse', but thats easy to build yourself, and much less of a hassle than some old gcc version can be. The latest (in a long string) of reasons for minimum compiler version upgrades was commit 5435f73d ("efi/x86: Fix build with gcc 4"). Ard points out that RHEL 7 uses gcc-4.8, but the people who stay back on old RHEL versions persumably also don't build their own kernels anyway. And maybe they should cross-built or just have a little side affair with a newer compiler? Acked-by:

1) In snd_hda_pick_fixup(), quirks are first matched by PCI SSID and then, if there is no match, by codec SSID. The Lenovo "ThinkPad X1 Carbon 7th" has an audio chip with PCI SSID 0x2292 and codec SSID 0x2293[1]. Therefore, fix the quirk meant for that device to match on .subdevice == 0x2292. 2) The "Thinkpad X1 Yoga 7th" does not exist. The companion product to the Carbon 7th is the Yoga 4th. That device has an audio chip with PCI SSID 0x2292 and codec SSID 0x2292[2]. Given the behavior of snd_hda_pick_fixup(), it is not possible to have a separate quirk for the Yoga based on SSID. Therefore, merge the quirks meant for the Carbon and Yoga. This preserves the current behavior for the Yoga.

When HDMI PCM devices are opened in a specific order, with at least one HDMI/DP receiver connected, ALSA PCM open fails to -EBUSY on the connected monitor, on recent Intel platforms (ICL/JSL and newer). While this is not a typical sequence, at least Pulseaudio does this every time when it is started, to discover the available PCMs. The rootcause is an invalid assumption in hdmi_add_pin(), where the total number of converters is assumed to be known at the time the function is called. On older Intel platforms this held true, but after ICL/JSL, the order how pins and converters are in the subnode list as returned by snd_hda_get_sub_nodes(), was changed. As a result, information for some converters was not stored to per_pin->mux_nids. And this means some pins cannot be connected to all converters, and application instead gets -EBUSY instead at open. The assumption that converters are always before pins in the subnode list, is not really a valid one. Fix the problem in hdmi_parse_codec() by introducing separate loops for discovering converters and pins.
