| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If ->run() fails, it can either free the data structures it allocated, or leave that task to ->free() which will be called on failures. However: md.c calls ->free() even if ->private_data is NULL, which causes problems in some personalities. raid0.c frees the data, but doesn't clear ->private_data, which will become a problem when we fix md.c So better fix both these issues at once.

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Kernfs supports two styles of read: direct_read and seqfile_read. The latter supports 'poll' correctly thanks to the update of '->event' in kernfs_seq_show. The former does not as '->event' is never updated on a read. So add an appropriate update in kernfs_file_direct_read(). This was noticed because some 'md' sysfs attributes were recently changed to use direct reads.

Remove the useless system clock (fclk). Avoid calling set_rate on the fixed rate UTMI/IPLL clock and remove useless IS_ENABLED(CONFIG_COMMON_CLK) tests (all at91 platforms have been moved to the CCF). This patch also fixes a bug introduced by 3440ef1 (ARM: at91/dt: fix USB high-speed clock to select UTMI), which was leaving the usb clock uninitialized and preventing the OHCI driver from setting the usb clock rate to 48MHz. This bug was caused by several things: 1/ usb clock drivers set the CLK_SET_RATE_GATE flag, which means the rate cannot be changed once the clock is prepared 2/ The EHCI driver was retrieving and preparing/enabling the uhpck clock which was in turn preparing its parent clock (the usb clock), thus preventing any rate change because of 1/ Fixes: 3440ef169100 ("ARM: at91/dt: fix USB high-speed clock to select UTMI") Signed-off-by: Boris Brezillon <boris.brezillon@free-electrons.com> Acked-by: Alan Stern <stern@rowland.harvard.edu> Acked-by: Nicolas Ferre <nicolas.ferre@atmel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
