The dprintk() macro relies on continuation lines. This is not a good practice and will break after commit 56387331 ("Merge branch 'printk-cleanups'"). So, instead of directly calling printk(), use pr_foo() macros, adding a \n leading char on each macro call. Signed-off-by:

Continuation lines without KERN_CONT won't work anymore. However, the way dprintk() was defined leads to the usage of continuation lines, with should be avoided when possible. So, redefine those macros. While hre, remove some dead code at av7110.c with also relies on continuation lines. Signed-off-by: -

This driver is old, and have lots of checkpatch violations. As we're touching a lot on this driver due to the printk conversions, let's run checkpatch --fix on it, in order to solve some of those issues. Also, do a few manual adjustments: - remove the FSF address and use the usual coding style for the initial comments; - use WARN_ON() instead of BUG_ON(); - remove an unused typedef; - break a few long lines.

Instead of calling printk() directly, use pr_foo() macros, as suggested at the Kernel's coding style. Please notice that a conversion to dev_foo() is not trivial, as several parts on this driver uses pr_cont(). Signed-off-by:

This driver uses a weird, non-standard macro to print errors. It allows hiding all messages, including error ones, with doesn't seem a good idea. Instead, replace it to pr_foo(), and, for error messages, use pr_err(). The remaining messages were previouly classified as notice, info or debug, but they all looked like debug messages. So, add a dprintk() macro using the "verbose" modprobe argument to select what will be displayed. Signed-off-by: -

Clock control indirectly requires access to MFC device, so call it only if we are sure that the device exists in s5p_mfc_release function. s5p_mfc_remove() calls s5p_mfc_final_pm(), which releases all PM related resources, including clocks, so any call to clocks related functions is not valid after s5p_mfc_final_pm().

Newer MFC hardware have internal clock gating feature, so additional software-triggered clock gating sometimes causes misbehavior of the MFC firmware and results in freeze or crash. This patch changes the driver to use software-triggered clock gating only when working with v5 MFC hardware, where it has been proven to work properly. Signed-off-by:

Currently, when incomplete frame is received in the middle of decoding, driver treats it as an error, so src/dst queue and clock are cleaned. Although it is obviously error case, it is needed to maintain video decoding in case of necessity. This patch supports skip incomplete frame to next. Signed-off-by:
