media: dvb: Add check on sp8870_readreg return

2021-06-03T07:09:41Z

[ Upstream commit c6d822c56e7fd29e6fa1b1bb91b98f6a1e942b3c ] The function sp8870_readreg returns a negative value when i2c_transfer fails so properly check for this and return the error if it happens.

Revert "media: dvb: Add check on sp8870_readreg"

2021-06-03T07:09:41Z

[ Upstream commit 47e4ff06fa7f5ba4860543a2913bbd0c164640aa ] This reverts commit 467a37fba93f2b4fe3ab597ff6a517b22b566882. Because of recent interactions with developers from @umn.edu, all commits from them have been recently re-reviewed to ensure if they were correct or not. Upon review, this commit was found to be incorrect for the reasons below, so it must be reverted. It will be fixed up "correctly" in a later kernel change. This commit is not properly checking for an error at all, so if a read succeeds from this device, it will error out.

media: m88ds3103: fix return value check in m88ds3103_probe()

2021-05-14T08:52:36Z

[ Upstream commit e61f9ea271933d987ab895c689fa37744f6fc27f ] In case of error, the function i2c_new_dummy_device() returns ERR_PTR() and never returns NULL. The NULL test in the return value check should be replaced with IS_ERR().

In preparation to enable -Wimplicit-fallthrough for Clang, fix multiple warnings by explicitly adding multiple break and a return statements instead of just letting the code fall through to the next case.

media: Replace HTTP links with HTTPS ones: SI2165 MEDIA DRIVER

2020-11-27T12:05:07Z

Rationale: Reduces attack surface on kernel devs opening the links for MITM as HTTPS traffic is much harder to manipulate. Deterministic algorithm: For each file: If not .svg: For each line: If doesn't contain `\bxmlns\b`: If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`: If both the HTTP and HTTPS versions return 200 OK and serve the same content: Replace HTTP with HTTPS.
