2009-08-12pata_at91: fix resource releaseTejun Heo1-13/+4
Julias Lawall discovered that pata_at91 wasn't freeing a memory region allocated with kzalloc() on init failure paths. Upon review, pata_at91 also seems to be doing unnecessary explicit resource releases for managed resources too. Convert memory allocation to managed one and drop unnecessary explicit resource releases.

2009-07-29libata: Updates and fixes for pata_at91 driverSergey Matyukevich1-31/+36
Please consider the following updates and fixes for pata_at91 driver. * Removed extra headers Here we need only static memory controller properties, which are contained in generic header at91sam9_smc.h. No need to include any specific headers for at91sam9260 SoC. * No harsh BUG_ON for get_clk in set_smc_timing function get_clk is now performed in driver probing function, probing fails if master clock is not available * Fixed uint/ulong mess in calc_mck_cycles function Signed-off-by: Sergey Matyukevich <geomatsi@gmail.com> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
2009-07-15drivers/ata: Move a dereference below a NULL testJulia Lawall1-1/+2
If the NULL test is necessary, then the dereference should be moved below the NULL test. The semantic patch that makes this change is as follows: (http://www.emn.fr/x-info/coccinelle/) // <smpl> @@ type T; expression E; identifier i,fld; statement S; @@ - T i = E->fld; + T i; ... when != E when != i if (E == NULL) S + i = E->fld; // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
