Input: cyapa_gen6 - fix out-of-bounds stack access

2020-12-30T10:26:07Z

commit f051ae4f6c732c231046945b36234e977f8467c6 upstream. gcc -Warray-bounds warns about a serious bug in cyapa_pip_retrieve_data_structure: drivers/input/mouse/cyapa_gen6.c: In function 'cyapa_pip_retrieve_data_structure.constprop': include/linux/unaligned/access_ok.h:40:17: warning: array subscript -1 is outside array bounds of 'struct retrieve_data_struct_cmd[1]' [-Warray-bounds] 40 | *((__le16 *)p) = cpu_to_le16(val); drivers/input/mouse/cyapa_gen6.c:569:13: note: while referencing 'cmd' 569 | } __packed cmd; | ^~~ Apparently the '-2' was added to the pointer instead of the value, writing garbage into the stack next to this variable.

Input: psmouse - add a newline when printing 'proto' by sysfs

[ Upstream commit 4aec14de3a15cf9789a0e19c847f164776f49473 ] When I cat parameter 'proto' by sysfs, it displays as follows.

Input: sentelic - fix error return when fsp_reg_write fails

2020-08-21T09:05:37Z

[ Upstream commit ea38f06e0291986eb93beb6d61fd413607a30ca4 ] Currently when the call to fsp_reg_write fails -EIO is not being returned because the count is being returned instead of the return value in retval. Fix this by returning the value in retval instead of count.

Input: synaptics - add a second working PNP_ID for Lenovo T470s

2020-06-22T07:05:00Z

[ Upstream commit 642aa86eaf8f1e6fe894f20fd7f12f0db52ee03c ] The Lenovo Thinkpad T470s I own has a different touchpad with "LEN007a" instead of the already included PNP ID "LEN006c". However, my touchpad seems to work well without any problems using RMI. So this patch adds the other PNP ID.

Input: synaptics - enable RMI on HP Envy 13-ad105ng

2020-04-02T13:28:16Z

commit 1369d0abe469fb4cdea8a5bce219d38cb857a658 upstream. This laptop (and perhaps other variants of the same model) reports an SMBus-capable Synaptics touchpad. Everything (including suspend and resume) works fine when RMI is enabled via the kernel command line, so let's add it to the whitelist.

Input: synaptics - remove the LEN0049 dmi id from topbuttonpad list

2020-02-19T18:51:53Z

commit 5179a9dfa9440c1781816e2c9a183d1d2512dc61 upstream. The Yoga 11e is using LEN0049, but it doesn't have a trackstick. Thus, there is no need to create a software top buttons row. However, it seems that the device works under SMBus, so keep it as part of the smbus_pnp_ids.
